However, defining a quantifiable figure of merit for entanglement in macroscopic solids is theoretically and experimentally challenging. At equilibrium the presence of entanglement can be diagnosed by extracting entanglement witnesses from spectroscopic observables and a nonequilibrium extension of this method could lead to the discovery of novel dynamical phenomena. Here, we propose a systematic approach to quantify the time-dependent quantum Fisher information and entanglement depth of transient states of quantum materials with time-resolved resonant inelastic x-ray scattering. Using a quarter-filled extended Hubbard model as an example, we benchmark the efficiency of this approach and predict a light-enhanced many-body entanglement due to the proximity to a phase boundary. Our work sets the stage for experimentally witnessing and controlling entanglement in light-driven quantum materials via ultrafast spectroscopic measurements.","lang":"eng"}],"volume":14,"date_created":"2023-08-09T13:06:59Z","year":"2023","_id":"13989","publication_status":"published","oa":1,"date_published":"2023-06-14T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/s41467-023-38540-3"}],"external_id":{"pmid":["37316515"],"arxiv":["2209.02283"]},"status":"public","extern":"1","intvolume":"        14","citation":{"ista":"Hales J, Bajpai U, Liu T, Baykusheva DR, Li M, Mitrano M, Wang Y. 2023.

The phase transition between non-trivial and trivial topological states is important, not only for basic materials science but also for next-generation technology, such as dissipation-free electronics4. It is therefore crucial to develop advanced probes that are suitable for a wide range of samples and environments. Here we demonstrate that circularly polarized laser-field-driven high-harmonic generation is distinctly sensitive to the non-trivial and trivial topological phases in the prototypical three-dimensional topological insulator bismuth selenide5. The phase transition is chemically initiated by reducing the spin–orbit interaction strength through the substitution of bismuth with indium atoms6,7. We find strikingly different high-harmonic responses of trivial and non-trivial topological surface states that manifest themselves as a conversion efficiency and elliptical dichroism that depend both on the driving laser ellipticity and the crystal orientation. The origins of the anomalous high-harmonic response are corroborated by calculations using the semiconductor optical Bloch equations with pairs of surface and bulk bands. As a purely optical approach, this method offers sensitivity to the electronic structure of the material, including its nonlinear response, and is compatible with a wide range of samples and sample environments.","lang":"eng"}],"date_updated":"2023-08-22T07:20:09Z","month":"09","oa_version":"None","type":"journal_article","page":"620-624","citation":{"ieee":"C.

We demonstrate the capabilities of VUV-TRPECD by resolving the chirality changes in time during the photodissociation of atomic iodine from two chiral molecules. We identify several general key features of TRPECD, which include the ability to probe dynamical chirality along the complete photochemical reaction path, the sensitivity to the local chirality of the evolving scattering potential, and the influence of electron scattering off dissociating photofragments.

How its properties evolve from isolated particles to the condensed phase is an open question of both fundamental and practical relevance. Here, we review recent work that has advanced the study of photoionization dynamics from atoms to molecules, clusters and the liquid phase. The first measurements of molecular photoionization delays have revealed the attosecond dynamics of electron emission from a molecular shape resonance and their sensitivity to the molecular potential. Using electron-ion coincidence spectroscopy these measurements have been extended from isolated molecules to clusters. A continuous increase of the delays with the water-cluster size has been observed up to a size of 4-5 molecules, followed by a saturation towards larger clusters. Comparison with calculations has revealed a correlation of the time delay with the spatial extension of the created electron hole. Using cylindrical liquid-microjet techniques, these measurements have also been extended to liquid water, revealing a delay relative to isolated water molecules that was very similar to the largest water clusters studied. Detailed modeling based on Monte-Carlo simulations confirmed that these delays are dominated by the contributions of the first two solvation shells, which agrees with the results of the cluster measurements. These combined results open the perspective of experimentally characterizing the delocalization of electronic wave functions in complex systems and studying their evolution on attosecond time scales.","lang":"eng"}],"date_updated":"2023-08-22T07:26:39Z","oa_version":"Published Version","month":"06","type":"journal_article","page":"520-528","date_created":"2023-08-09T13:08:15Z","volume":76,"year":"2022","_id":"13993","publication_identifier":{"issn":["0009-4293"],"eissn":["2673-2424"]},"quality_controlled":"1","doi":"10.2533/chimia.2022.520","language":[{"iso":"eng"}],"issue":"6","keyword":["General Medicine","General Chemistry"],"day":"29","author":[{"first_name":"Xiaochun","last_name":"Gong","full_name":"Gong, Xiaochun"},{"full_name":"Jordan, Inga","first_name":"Inga","last_name":"Jordan"},{"full_name":"Huppert, Martin","last_name":"Huppert","first_name":"Martin"},{"first_name":"Saijoscha","last_name":"Heck","full_name":"Heck, Saijoscha"},{"first_name":"Denitsa Rangelova","last_name":"Baykusheva","full_name":"Baykusheva, Denitsa Rangelova","id":"71b4d059-2a03-11ee-914d-dfa3beed6530"},{"full_name":"Jelovina, Denis","first_name":"Denis","last_name":"Jelovina"},{"full_name":"Schild, Axel","first_name":"Axel","last_name":"Schild"},{"full_name":"Wörner, Hans Jakob","first_name":"Hans Jakob","last_name":"Wörner"}],"title":"Attosecond photoionization dynamics: from molecules over clusters to the liquid phase","publisher":"Swiss Chemical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","scopus_import":"1","article_type":"original","publication":"Chimia"},{"title":"Ultrafast renormalization of the on-site Coulomb repulsion in a cuprate superconductor","arxiv":1,"article_number":"011013","day":"20","author":[{"first_name":"Denitsa Rangelova","last_name":"Baykusheva","full_name":"Baykusheva, Denitsa Rangelova","id":"71b4d059-2a03-11ee-914d-dfa3beed6530"},{"first_name":"Hoyoung","last_name":"Jang","full_name":"Jang, Hoyoung"},{"first_name":"Ali A.","last_name":"Husain","full_name":"Husain, Ali A."},{"full_name":"Lee, Sangjun","first_name":"Sangjun","last_name":"Lee"},{"first_name":"Sophia F. R.","last_name":"TenHuisen","full_name":"TenHuisen, Sophia F. R."},{"last_name":"Zhou","first_name":"Preston","full_name":"Zhou, Preston"},{"full_name":"Park, Sunwook","first_name":"Sunwook","last_name":"Park"},{"first_name":"Hoon","last_name":"Kim","full_name":"Kim, Hoon"},{"last_name":"Kim","first_name":"Jin-Kwang","full_name":"Kim, Jin-Kwang"},{"full_name":"Kim, Hyeong-Do","last_name":"Kim","first_name":"Hyeong-Do"},{"full_name":"Kim, Minseok","last_name":"Kim","first_name":"Minseok"},{"first_name":"Sang-Youn","last_name":"Park","full_name":"Park, Sang-Youn"},{"last_name":"Abbamonte","first_name":"Peter","full_name":"Abbamonte, Peter"},{"full_name":"Kim, B. J.","first_name":"B. J.","last_name":"Kim"},{"first_name":"G. D.","last_name":"Gu","full_name":"Gu, G. D."},{"last_name":"Wang","first_name":"Yao","full_name":"Wang, Yao"},{"first_name":"Matteo","last_name":"Mitrano","full_name":"Mitrano, Matteo"}],"article_processing_charge":"No","scopus_import":"1","article_type":"original","publication":"Physical Review X","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Physical Society","quality_controlled":"1","doi":"10.1103/physrevx.12.011013","publication_identifier":{"eissn":["2160-3308"]},"language":[{"iso":"eng"}],"issue":"1","keyword":["General Physics and Astronomy"],"date_created":"2023-08-09T13:08:26Z","volume":12,"date_updated":"2023-08-22T07:28:38Z","abstract":[{"text":"Ultrafast lasers are an increasingly important tool to control and stabilize emergent phases in quantum materials. Among a variety of possible excitation protocols, a particularly intriguing route is the direct light engineering of microscopic electronic parameters, such as the electron hopping and the local Coulomb repulsion (Hubbard \r\nU). In this work, we use time-resolved x-ray absorption spectroscopy to demonstrate the light-induced renormalization of the Hubbard U in a cuprate superconductor, La1.905Ba0.095CuO4. We show that intense femtosecond laser pulses induce a substantial redshift of the upper Hubbard band while leaving the Zhang-Rice singlet energy unaffected. By comparing the experimental data to time-dependent spectra of single- and three-band Hubbard models, we assign this effect to an approximately 140-meV reduction of the on-site Coulomb repulsion on the copper sites. Our demonstration of a dynamical Hubbard U renormalization in a copper oxide paves the way to a novel strategy for the manipulation of superconductivity and magnetism as well as to the realization of other long-range-ordered phases in light-driven quantum materials.","lang":"eng"}],"type":"journal_article","oa_version":"Published Version","month":"01","_id":"13994","year":"2022","main_file_link":[{"url":"https://doi.org/10.1103/PhysRevX.12.011013","open_access":"1"}],"date_published":"2022-01-20T00:00:00Z","publication_status":"published","oa":1,"citation":{"ieee":"D.

We find delays of up to ∼600 as in the ionization out of the highest occupied molecular orbital (HOMO) with a strong dependence on the emission direction and a pronounced asymmetry along the dissociation axis. Comparison with quantum-scattering calculations traces the asymmetries to the interference of a small subset of partial waves at low kinetic energies and, additionally, to the interference of two overlapping shape resonances in the HOMO-1 channel.

In particular, we focus on the process of nonperturbative high-order harmonic generation from the paradigmatic three-dimensional topological insulator bismuth selenide (Bi2Se3) subjected to intense midinfrared laser fields. We analyze the contributions from the spin-orbit-coupled bulk states and the topological surface bands separately and reveal a major difference in how their harmonic yields depend on the ellipticity of the laser field. Bulk harmonics show a monotonic decrease in their yield as the ellipticity increases, in a manner reminiscent of high harmonic generation in gaseous media. However, the surface contribution exhibits a highly nontrivial dependence, culminating with a maximum for circularly polarized fields. We attribute the observed anomalous behavior to (i) the enhanced amplitude and the circular pattern of the interband dipole and the Berry connections in the vicinity of the Dirac point and (ii) the influence of the higher-order, hexagonal warping terms in the Hamiltonian, which are responsible for the hexagonal deformation of the energy surface at higher momenta. The latter are associated directly with spin-orbit-coupling parameters.

Here we show that, when high-harmonics are detected from the input surface of a magnesium oxide crystal, a bichromatic probing of the XUV emission shows a clear synchronization largely consistent with a semiclassical model of electron–hole recollisions in bulk solids. On the other hand, the bichromatic spectrogram of harmonics originating from the exit surface of the 200 μm-thick crystal is strongly modified, indicating the influence of laser field distortions during propagation. Our tracking of sub-cycle electron and hole re-collisions at XUV energies is relevant to the development of solid-state sources of attosecond pulses.","lang":"eng"}],"oa_version":"Preprint","month":"06","type":"journal_article","extern":"1","intvolume":"        53","citation":{"short":"G.

Ionization-delay measurements in atomic targets provide a wealth of information about the timing of the photoelectric effect, resonances, electron correlations and transport. However, extending this approach to molecules presents challenges, such as identifying the correct ionization channels and the effect of the anisotropic molecular landscape on the measured delays. Here, we measure ionization delays from ethyl iodide around a giant dipole resonance. By using the theoretical value for the iodine atom as a reference, we disentangle the contribution from the functional ethyl group, which is responsible for the characteristic chemical reactivity of a molecule. We find a substantial additional delay caused by the presence of a functional group, which encodes the effect of the molecular potential on the departing electron. Such information is inaccessible to the conventional approach of measuring photoionization cross-sections. The results establish ionization-delay measurements as a valuable tool in investigating the electronic properties of molecules."}],"page":"778-783","date_created":"2023-08-09T13:10:07Z","volume":16,"year":"2020","_id":"13999"},{"date_created":"2023-08-09T13:10:23Z","title":"Attosecond Molecular Dynamics and Spectroscopy","type":"book_chapter","oa_version":"None","month":"09","date_updated":"2023-08-22T09:25:07Z","abstract":[{"lang":"eng","text":"This chapter presents an overview of the state of the art in attosecond time-resolved spectroscopy.

Therefore, it is essential to understand and ultimately control the evolution of molecular chirality during chemical reactions. Although highly sophisticated techniques for the controlled synthesis of chiral molecules have been developed, the observation of chirality on the natural femtosecond time scale of a chemical reaction has so far remained out of reach in the gas phase. Here, we demonstrate a general experimental technique, based on high-harmonic generation in tailored laser fields, and apply it to probe the time evolution of molecular chirality during the photodissociation of 2-iodobutane. These measurements show a change in sign and a pronounced increase in the magnitude of the chiral response over the first 100 fs, followed by its decay within less than 500 fs, revealing the photodissociation to achiral products. The observed time evolution is explained in terms of the variation of the electric and magnetic transition-dipole moments between the lowest electronic states of the cation as a function of the reaction coordinate. These results open the path to investigations of the chirality of molecular-reaction pathways, light-induced chirality in chemical processes, and the control of molecular chirality through tailored laser pulses.","lang":"eng"}],"volume":116,"date_created":"2023-08-09T13:10:36Z","external_id":{"arxiv":["1906.10818"],"pmid":["31723044"]},"status":"public","extern":"1","intvolume":"       116","citation":{"ieee":"D.

Ionization delay measurements in atomic targets provide a wealth of information about the timing of the photoelectric effect [2], resonances, electron correlations and transport. The extension of this approach to molecules, however, presents great challenges. In addition to the difficulty of identifying correct ionization channels, it is hard to disentangle the role of the anisotropic molecular landscape from the delays inherent to the excitation process itself. Here, we present the measurements of ionization delays from ethyl iodide around the 4d giant dipole resonance of iodine. We employ attosecond streaking spectroscopy, which enables to disentangle the contribution to the delay from the functional ethyl group, being responsible for the characteristic chemical reactivity of the molecule. An attosecond extreme ultraviolet (XUV) pulse ionizes the molecule around the energy of the giant resonance and the released electron is exposed to the ponderomotive force of a synchronized near-infrared (NIR) field, which yields a streaking spectrogram (see figure). Comparative phase analysis of the spectrograms corresponding to iodine 4d and neon 2p emission permits extracting overall photoemission delays for ethyl iodide. The data is recorded for multiple photon energies around the iodine 4d resonance and compared to classical Wigner propagation [3] and quantum scattering [4] calculations. Here the outgoing electron, produced via inner shell ionization of the iodine atom in ethyl iodide, and thereby hardly influenced by the molecular potential during the birth process, acquires the necessary information about the influence of the functional ethyl group during its propagation. We find significant delay contributions that can distinguish between different functional groups, providing a sensitive probe of the local molecular environment [5]. This would stimulate to perform further angle resolved measurements in molecules to probe the potential landscape in three dimension."}],"date_updated":"2023-08-22T09:32:56Z","_id":"14002","publication":"2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference","scopus_import":"1","article_processing_charge":"No","publisher":"Institute of Electrical and Electronics Engineers","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2019"},{"publication_identifier":{"eissn":["2160-3308"]},"doi":"10.1103/physrevx.8.031060","quality_controlled":"1","keyword":["General Physics and Astronomy"],"language":[{"iso":"eng"}],"issue":"3","author":[{"id":"71b4d059-2a03-11ee-914d-dfa3beed6530","full_name":"Baykusheva, Denitsa Rangelova","first_name":"Denitsa Rangelova","last_name":"Baykusheva"},{"full_name":"Wörner, Hans Jakob","first_name":"Hans Jakob","last_name":"Wörner"}],"day":"01","title":"Chiral discrimination through bielliptical high-harmonic spectroscopy","article_number":"031060","publisher":"American Physical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication":"Physical Review X","article_processing_charge":"No","scopus_import":"1","article_type":"original","publication_status":"published","oa":1,"date_published":"2018-07-01T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1103/PhysRevX.8.031060"}],"status":"public","extern":"1","intvolume":"         8","citation":{"apa":"Baykusheva, D.

The observation and quantification of chirality-sensitive signals, however, remains extremely challenging, especially on ultrafast timescales and in dilute media. Here, we describe the experimental realization of an all-optical and ultrafast scheme for detecting chiral dynamics in molecules. This technique is based on high-harmonic generation by a combination of two-color counterrotating femtosecond laser pulses with polarization states tunable from linear to circular. We demonstrate two different implementations of chiral-sensitive high-harmonic spectroscopy on an ensemble of randomly oriented methyloxirane molecules in the gas phase. Using two elliptically polarized fields, we observe that the ellipticities maximizing the harmonic signal reach up to \r\n4.4\r\n±\r\n0.2\r\n%\r\n (at 17.6 eV). Using two circularly polarized fields, we observe circular dichroisms ranging up to \r\n13\r\n±\r\n6\r\n%\r\n (28.3–33.1 eV). Our theoretical analysis confirms that the observed chiral response originates from subfemtosecond electron dynamics driven by the magnetic component of the driving laser field. This assignment is supported by the experimental observation of a strong intensity dependence of the chiral effects and its agreement with theory. We moreover report and explain a pronounced variation of the signal strength and dichroism with the driving-field ellipticities and harmonic orders. Finally, we demonstrate the sensitivity of the experimental observables to the shape of the electron hole. This technique for chiral discrimination will yield femtosecond temporal resolution when integrated in a pump-probe scheme and subfemtosecond resolution on chiral charge migration in a self-probing scheme."}],"oa_version":"Published Version","type":"journal_article","month":"07","volume":8,"date_created":"2023-08-10T06:34:48Z","year":"2018","_id":"14003"},{"date_created":"2023-08-10T06:35:51Z","volume":119,"abstract":[{"text":"High-harmonic spectroscopy driven by circularly polarized laser pulses and their counterrotating second harmonic is a new branch of attosecond science which currently lacks quantitative interpretations.

These results are used to derive formulae for the delays measured by two-photon attosecond interferometry based on an attosecond pulse train and a dressing femtosecond infrared pulse. These effective delays are first expressed in the molecular frame where maximal information about the molecular photoionization dynamics is available. The effects of averaging over the emission direction of the electron and the molecular orientation are introduced analytically. We illustrate this general formalism for the case of two polyatomic molecules. N2O serves as an example of a polar linear molecule characterized by complex photoionization dynamics resulting from the presence of molecular shape resonances. H2O illustrates the case of a non-linear molecule with comparably simple photoionization dynamics resulting from a flat continuum. Our theory establishes the foundation for interpreting measurements of the photoionization dynamics of all molecules by attosecond metrology."}],"month":"03","type":"journal_article","oa_version":"None","language":[{"iso":"eng"}],"issue":"12","keyword":["Physical and Theoretical Chemistry","General Physics and Astronomy"],"quality_controlled":"1","doi":"10.1063/1.4977933","publication_identifier":{"issn":["0021-9606"],"eissn":["1089-7690"]},"article_processing_charge":"No","scopus_import":"1","article_type":"original","publication":"The Journal of Chemical Physics","pmid":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"AIP Publishing","title":"Theory of attosecond delays in molecular photoionization","article_number":"124306","day":"28","author":[{"id":"71b4d059-2a03-11ee-914d-dfa3beed6530","full_name":"Baykusheva, Denitsa Rangelova","last_name":"Baykusheva","first_name":"Denitsa Rangelova"},{"last_name":"Wörner","first_name":"Hans Jakob","full_name":"Wörner, Hans Jakob"}]},{"quality_controlled":"1","doi":"10.1088/1361-6455/aa62b5","publication_identifier":{"issn":["0953-4075"],"eissn":["1361-6455"]},"language":[{"iso":"eng"}],"issue":"7","keyword":["Condensed Matter Physics","Atomic and Molecular Physics","and Optics"],"title":"Comment on ‘Time delays in molecular photoionization’","arxiv":1,"article_number":"078002","day":"15","author":[{"last_name":"Baykusheva","first_name":"Denitsa Rangelova","id":"71b4d059-2a03-11ee-914d-dfa3beed6530","full_name":"Baykusheva, Denitsa Rangelova"},{"full_name":"Wörner, Hans Jakob","first_name":"Hans Jakob","last_name":"Wörner"}],"article_processing_charge":"No","scopus_import":"1","article_type":"letter_note","publication":"Journal of Physics B: Atomic, Molecular and Optical Physics","publisher":"IOP Publishing","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"url":"https://arxiv.org/abs/1611.09352","open_access":"1"}],"date_published":"2017-03-15T00:00:00Z","oa":1,"publication_status":"published","citation":{"short":"D.R.
