Our focus is on systems where isotropic or anisotropic impurity-boson interactions support a shallow bound state. To study the fate of the angulon in the vicinity of bound-state formation, we formulate a beyond-linear-coupling angulon Hamiltonian. First, we use it to study attractive, spherically symmetric impurity-boson interactions for which the linear rotor can be mapped onto a static impurity. The well-known polaron formalism provides an adequate description in this limit. Second, we consider anisotropic potentials, and show that the presence of a shallow bound state with pronounced anisotropic character leads to a many-body instability that washes out the angulon dynamics.","lang":"eng"}],"date_updated":"2024-01-23T10:51:09Z","month":"01","type":"journal_article","oa_version":"None","volume":109,"date_created":"2024-01-21T23:00:57Z","status":"public","intvolume":"       109","citation":{"apa":"Dome, T., Volosniev, A., Ghazaryan, A., Safari, L., Schmidt, R., &#38; Lemeshko, M.

This approximation assumes that the timescale of the laser-molecule interaction is significantly shorter than the internal rotational period of the molecule, resulting in the rotational motion being instantaneously “frozen” during the interaction. This simplified description of the laser-molecule interaction is incorporated in various theoretical models predicting rotational dynamics of molecules driven by short laser pulses. In this theoretical work, we develop an effective theory for ultrashort laser pulses by examining the full time-evolution operator and solving the time-dependent Schrödinger equation at the operator level. Our findings reveal a critical angular momentum, lcrit, at which the impulsive limit breaks down. In other words, the validity of the sudden approximation depends not only on the pulse duration but also on its intensity, since the latter determines how many angular momentum states are populated. We explore both ultrashort multicycle (Gaussian) pulses and the somewhat less studied half-cycle pulses, which produce distinct effective potentials. We discuss the limitations of the impulsive limit and propose a method that rescales the effective matrix elements, enabling an improved and more accurate description of laser-molecule interactions.","lang":"eng"}],"date_updated":"2024-02-26T09:45:20Z","oa_version":"Preprint","month":"02","type":"journal_article","intvolume":"       109","citation":{"short":"V.

In the nonperturbative regime, where our theory cannot be reduced to any of the earlier models, we reveal that the polaron is characterized by large coherence length and a roughly tenfold increase of the effective mass as compared to the bare mass.

Understanding the interplay between these two subsystems is a challenging problem, but it is this coupling that is widely conjectured to be responsible for the unique behavior of photocarriers in these materials. In this work, we use the fact that the polarizability of the organic cation strongly depends on the ambient electrostatic environment to put the molecule forward as a sensitive probe of the local crystal fields inside the lattice cell. We measure the average polarizability of the C/N–H bond stretching mode by means of infrared spectroscopy, which allows us to deduce the character of the motion of the cation molecule, find the magnitude of the local crystal field, and place an estimate on the strength of the hydrogen bond between the hydrogen and halide atoms. Our results pave the way for understanding electric fields in lead-halide perovskites using infrared bond spectroscopy.","lang":"eng"}],"date_updated":"2023-07-19T06:59:19Z","oa_version":"Published Version","month":"07","type":"journal_article","page":"6309-6314","_id":"13251","year":"2023","acknowledgement":"We thank Bingqing Cheng and Hong-Zhou Ye for valuable discussions; Y.W.’s work at IST Austria was supported through ISTernship summer internship program funded by OeADGmbH; D.L. and Z.A. acknowledge support by IST Austria (ISTA); M.L. acknowledges support by the European Research Council (ERC) Starting Grant No. 801770 (ANGULON).\r\nA.A.Z. and O.M.B. acknowledge support by KAUST.","quality_controlled":"1","doi":"10.1021/acs.jpclett.3c01158","publication_identifier":{"eissn":["1948-7185"]},"language":[{"iso":"eng"}],"issue":"27","isi":1,"keyword":["General Materials Science","Physical and Theoretical Chemistry"],"project":[{"grant_number":"801770","call_identifier":"H2020","_id":"2688CF98-B435-11E9-9278-68D0E5697425","name":"Angulon: physics and applications of a new quasiparticle"}],"title":"Bond polarizability as a probe of local crystal fields in hybrid lead-halide perovskites","arxiv":1,"day":"05","file":[{"creator":"dernst","content_type":"application/pdf","relation":"main_file","file_size":2121252,"success":1,"file_name":"2023_JourPhysChemistry_Wei.pdf","access_level":"open_access","date_created":"2023-07-19T06:55:39Z","checksum":"c0c040063f06a51b9c463adc504f1a23","date_updated":"2023-07-19T06:55:39Z","file_id":"13253"}],"author":[{"full_name":"Wei, Yujing","orcid":"0000-0001-8913-9719","id":"0c5ff007-2600-11ee-b896-98bd8d663294","last_name":"Wei","first_name":"Yujing"},{"first_name":"Artem","last_name":"Volosniev","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0393-5525","full_name":"Volosniev, Artem"},{"id":"40D8A3E6-F248-11E8-B48F-1D18A9856A87","full_name":"Lorenc, Dusan","last_name":"Lorenc","first_name":"Dusan"},{"full_name":"Zhumekenov, Ayan A.","last_name":"Zhumekenov","first_name":"Ayan A."},{"full_name":"Bakr, Osman M.","last_name":"Bakr","first_name":"Osman M."},{"first_name":"Mikhail","last_name":"Lemeshko","orcid":"0000-0002-6990-7802","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail"},{"first_name":"Zhanybek","last_name":"Alpichshev","orcid":"0000-0002-7183-5203","id":"45E67A2A-F248-11E8-B48F-1D18A9856A87","full_name":"Alpichshev, Zhanybek"}],"ec_funded":1,"article_processing_charge":"Yes (via OA deal)","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"publication":"The Journal of Physical Chemistry Letters","department":[{"_id":"MiLe"},{"_id":"ZhAl"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Chemical Society"},{"quality_controlled":"1","doi":"10.1103/PhysRevB.108.045115","publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"language":[{"iso":"eng"}],"issue":"4","project":[{"name":"A path-integral approach to composite impurities","call_identifier":"FWF","_id":"26986C82-B435-11E9-9278-68D0E5697425","grant_number":"M02641"},{"name":"Algebro-Geometric Applications of Factorization Homology","_id":"26B96266-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"M02751"},{"grant_number":"P29902","call_identifier":"FWF","_id":"26031614-B435-11E9-9278-68D0E5697425","name":"Quantum rotations in the presence of a many-body environment"},{"_id":"2688CF98-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Angulon: physics and applications of a new quasiparticle","grant_number":"801770"}],"arxiv":1,"title":"Diagrammatic Monte Carlo for electronic correlation in molecules: High-order many-body perturbation theory with low scaling","article_number":"045115","day":"15","author":[{"last_name":"Bighin","first_name":"Giacomo","id":"4CA96FD4-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8823-9777","full_name":"Bighin, Giacomo"},{"first_name":"Quoc P","last_name":"Ho","full_name":"Ho, Quoc P","orcid":"0000-0001-6889-1418","id":"3DD82E3C-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Lemeshko, Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6990-7802","first_name":"Mikhail","last_name":"Lemeshko"},{"last_name":"Tscherbul","first_name":"T.

Recently, this has changed as isotopic fractionation that deviates from classical mass dependence was reported both in vitro and in vivo. In these cases, the isotopic effect correlates with the nuclear magnetic spin. Here, we show nuclear spin effects using stable oxygen isotopes (16O, 17O, and 18O) in two separate setups: an artificial dioxygen production system and biological aquaporin channels in cells. We observe that oxygen dynamics in chiral environments (in particular its transport) depend on nuclear spin, suggesting future applications for controlled isotope separation to be used, for instance, in NMR. To demonstrate the mechanism behind our findings, we formulate theoretical models based on a nuclear-spin-enhanced switch between electronic spin states. Accounting for the role of nuclear spin in biology can provide insights into the role of quantum effects in living systems and help inspire the development of future biotechnology solutions.","lang":"eng"}],"date_updated":"2023-10-17T11:45:25Z","_id":"14037","year":"2023","acknowledgement":"N.M.-S. acknowledges the support of the Ministry of Energy, Israel, as part of the scholarship program for graduate students in the fields of energy.

The time-dependent degree of alignment measured, exhibits a periodic, gradually decreasing structure that deviates qualitatively from that expected for gas-phase dimers. Comparison to alignment dynamics calculated from the time-dependent rotational Schrödinger equation shows that the deviation is due to the alignment dependent interaction between the dimer and the droplet surface. This interaction confines the dimer to the tangential plane of the droplet surface at the point where it resides and is the reason that the observed alignment dynamics is also well described by a 2D quantum rotor model."}],"type":"journal_article","month":"08","oa_version":"Preprint","date_created":"2023-08-27T22:01:16Z","volume":131},{"oa_version":"Published Version","type":"journal_article","month":"01","date_updated":"2023-02-20T07:02:00Z","abstract":[{"lang":"eng","text":"Brownian motion of a mobile impurity in a bath is affected by spin-orbit coupling (SOC). Here, we discuss a Caldeira-Leggett-type model that can be used to propose and interpret quantum simulators of this problem in cold Bose gases. First, we derive a master equation that describes the model and explore it in a one-dimensional (1D) setting. To validate the standard assumptions needed for our derivation, we analyze available experimental data without SOC; as a byproduct, this analysis suggests that the quench dynamics of the impurity is beyond the 1D Bose-polaron approach at temperatures currently accessible in a cold-atom laboratory—motion of the impurity is mainly driven by dissipation. For systems with SOC, we demonstrate that 1D spin-orbit coupling can be gauged out even in the presence of dissipation—the information about SOC is incorporated in the initial conditions. Observables sensitive to this information (such as spin densities) can be used to study formation of steady spin polarization domains during quench dynamics."}],"volume":5,"file_date_updated":"2023-02-13T10:38:10Z","date_created":"2023-02-10T09:02:26Z","acknowledgement":"We thank Rafael Barfknecht for help at the initial stages of this project; Fabian Brauneis for useful discussions; Miguel A.

A periodically kicked molecular rotor can be mapped onto a “crystalline” lattice in angular momentum space. This allows us to define quasimomenta and the band structure in the Floquet representation, by analogy with the Bloch waves of solid-state physics. Applying laser pulses spaced by 1/3 of the molecular rotational period creates a lattice with three atoms per unit cell with staggered hopping. Within the synthetic dimension of the laser strength, we discover Dirac cones with topological charges. These Dirac cones, topologically protected by reflection and time-reversal symmetry, are reminiscent of (although not equivalent to) that seen in graphene. They—and the corresponding edge states—are broadly tunable by adjusting the laser strength and can be observed in present-day experiments by measuring molecular alignment and populations of rotational levels. This paves the way to study controllable topological physics in gas-phase experiments with small molecules as well as to classify dynamical molecular states by their topological invariants."}],"oa_version":"Preprint","month":"03","type":"journal_article","_id":"12788","year":"2023","acknowledgement":"M.

Here, we propose a coherent state ansatz in the co-rotating frame, which provides a comprehensive theoretical description of angulons. We reveal the quasiparticle properties, such as energies, quasiparticle weights, and spectral functions, and show that our ansatz yields a persistent decrease in the impurity’s rotational constant due to many-body dressing, which is consistent with experimental observations. From our study, a picture of the angulon emerges as an effective spin interacting with a magnetic field that is self-consistently generated by the molecule’s rotation. Moreover, we discuss rotational spectroscopy, which focuses on the response of rotating molecules to a laser perturbation in the linear response regime. Importantly, we take into account initial-state interactions that have been neglected in prior studies and reveal their impact on the excitation spectrum. To examine the angulon instability regime, we use a single-excitation ansatz and obtain results consistent with experiments, in which a broadening of spectral lines is observed while phonon wings remain highly suppressed due to initial-state interactions."}],"date_updated":"2023-08-01T14:08:47Z","type":"journal_article","month":"04","oa_version":"Published Version","_id":"12831","year":"2023","acknowledgement":"We thank Ignacio Cirac, Christian Schmauder, and Henrik Stapelfeldt for their valuable discussions.

Moreover, we derive the critical line that separates these regimes in the parameter space. In the thermodynamic limit, this critical line determines the maximum number of bosons that can be bound by the impurity potential, forming an artificial atom. Second, we validate the mean-field results using the flow equation approach and the multi-layer multi-configuration time-dependent Hartree method for atomic mixtures.

Rev. A 104 L061303). This calls for theoretical approaches that go beyond explaining renormalized values of molecular spectroscopic constants, which suffices when only the lowest few rotational states are involved. As the first step in this direction, here we present a basic quantum mechanical model describing highly excited rotational states of molecules in superfluid helium nanodroplets. We show that a linear molecule immersed in a superfluid can be seen as an effective symmetric top, similar to the rotational structure of radicals, such as OH or NO, but with the angular momentum of the superfluid playing the role of the electronic angular momentum in free molecules. The simple theory sheds light onto what happens when the rotational angular momentum of the molecule increases beyond the lowest excited states accessible by infrared spectroscopy. In addition, the model allows to estimate the effective rotational and centrifugal distortion constants for a broad range of species and to explain the crossover between light and heavy molecules in superfluid 4He in terms of the many-body wavefunction structure. Some of the above mentioned insights can be acquired by analyzing a simple 2 × 2 matrix."}],"date_updated":"2024-08-07T07:16:52Z","oa_version":"Published Version","type":"journal_article","month":"08","_id":"11998","year":"2022","acknowledgement":"IC acknowledges the support by the European Union's Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 665385.

It is known, however, that the geometry and topology of space can have significant effects on quantum statistics for particles moving on it. Here, we have undertaken the first step toward realizing the emerging fractional statistics for particles restricted to move on the sphere instead of on the plane. We show that such a model arises naturally in the context of quantum impurity problems. In particular, we demonstrate a setup in which the lowest-energy spectrum of two linear bosonic or fermionic molecules immersed in a quantum many-particle environment can coincide with the anyonic spectrum on the sphere. This paves the way toward the experimental realization of anyons on the sphere using molecular impurities. Furthermore, since a change in the alignment of the molecules corresponds to the exchange of the particles on the sphere, such a realization reveals a novel type of exclusion principle for molecular impurities, which could also be of use as a powerful technique to measure the statistics parameter. Finally, our approach opens up a simple numerical route to investigate the spectra of many anyons on the sphere. Accordingly, we present the spectrum of two anyons on the sphere in the presence of a Dirac monopole field."}],"type":"journal_article","month":"01","oa_version":"Preprint","citation":{"short":"M.

We show that entanglement between the two degrees of freedom weakens localization due to the upper bound imposed on the inverse participation ratio by purity of a quantum state. We perform numerical calculations for a two-particle system bound by a harmonic force in a 1D disordered lattice and a rigid rotor in a 2D disordered lattice. We illustrate that the coupling has a dramatic effect on localization properties, even with a small number of internal states participating in quantum dynamics."}],"date_updated":"2024-02-29T12:34:10Z","type":"journal_article","month":"10","oa_version":"Preprint","citation":{"mla":"Suzuki, Fumika, et al. “Anderson Localization of Composite Particles.” <i>Physical Review Letters</i>, vol. 127, no. 16, 160602, American Physical Society , 2021, doi:<a href=\"https://doi.org/10.1103/physrevlett.127.160602\">10.1103/physrevlett.127.160602</a>.","ista":"Suzuki F, Lemeshko M, Zurek WH, Krems RV. 2021.
