We demonstrate that at low fluence of the fs alignment pulse, the molecule and its solvation shell can be set into coherent collective rotation lasting long enough to form revivals. With increasing fluence, however, the revivals disappear -- instead, rotational dynamics as rapid as for an isolated molecule is observed during the first few picoseconds. Classical calculations trace this phenomenon to transient decoupling of the molecule from its He shell. Our results open novel opportunities for studying non-equilibrium solute-solvent dynamics and quantum thermalization. "}],"citation":{"ama":"Shepperson B, Søndergaard A, Christiansen L, et al.

One of the pivotal challenges in this field is the designation of a consistent interpretation framework within which we can describe quantitatively the universal features of those systems. Here we analyze in a detailed manner the principal experimental data and compare them quantitatively with the approach based on a single-band model of strongly correlated electrons supplemented with strong antiferromagnetic (super)exchange interaction (the so-called t−J−U model). The model rationale is provided by estimating its microscopic parameters on the basis of the three-band approach for the Cu-O plane. We use our original full Gutzwiller wave-function solution by going beyond the renormalized mean-field theory (RMFT) in a systematic manner. Our approach reproduces very well the observed hole doping (δ) dependence of the kinetic-energy gain in the superconducting phase, one of the principal non-Bardeen-Cooper-Schrieffer features of the cuprates. The calculated Fermi velocity in the nodal direction is practically δ-independent and its universal value agrees very well with that determined experimentally. Also, a weak doping dependence of the Fermi wave vector leads to an almost constant value of the effective mass in a pure superconducting phase which is both observed in experiment and reproduced within our approach. An assessment of the currently used models (t−J, Hubbard) is carried out and the results of the canonical RMFT as a zeroth-order solution are provided for comparison to illustrate the necessity of the introduced higher-order contributions."}],"date_created":"2018-12-11T11:50:29Z","_id":"1162","scopus_import":"1","doi":"10.1103/PhysRevB.95.024506","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1606.03247"}],"publication_identifier":{"issn":["24699950"]},"title":"Universal properties of high temperature superconductors from real space pairing t-J-U model and its quantitative comparison with experiment","publication_status":"published","oa_version":"Submitted Version","article_processing_charge":"No","language":[{"iso":"eng"}],"isi":1,"month":"01","publist_id":"6195","status":"public","publisher":"American Physical Society","type":"journal_article","external_id":{"isi":["000391852800006"]},"date_published":"2017-01-13T00:00:00Z","issue":"2","project":[{"grant_number":"291734","call_identifier":"FP7","name":"International IST Postdoc Fellowship Programme","_id":"25681D80-B435-11E9-9278-68D0E5697425"}],"day":"13","quality_controlled":"1"},{"publisher":"IOP Publishing Ltd.","date_published":"2017-01-16T00:00:00Z","external_id":{"isi":["000393955500001"]},"type":"journal_article","language":[{"iso":"eng"}],"status":"public","publist_id":"6194","month":"01","isi":1,"day":"16","quality_controlled":"1","project":[{"grant_number":"291734","call_identifier":"FP7","name":"International IST Postdoc Fellowship Programme","_id":"25681D80-B435-11E9-9278-68D0E5697425"}],"issue":"8","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","author":[{"first_name":"Marcin","last_name":"Wysokiński","full_name":"Wysokiński, Marcin"},{"first_name":"Jan","last_name":"Kaczmarczyk","id":"46C405DE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1629-3675","full_name":"Kaczmarczyk, Jan"}],"volume":29,"intvolume":"        29","publication":"Journal of Physics: Condensed Matter","ec_funded":1,"date_updated":"2023-09-20T11:25:32Z","department":[{"_id":"MiLe"}],"publication_identifier":{"issn":["09538984"]},"doi":"10.1088/1361-648X/aa532f","scopus_import":"1","article_processing_charge":"No","oa_version":"None","title":"Unconventional superconductivity in generalized Hubbard model role of electron–hole symmetry breaking terms","publication_status":"published","abstract":[{"lang":"eng","text":"We investigate the effect of the electron-hole (e-h) symmetry breaking on d-wave superconductivity induced by non-local effects of correlations in the generalized Hubbard model.

Both terms lead to a pronounced asymmetry of the superconducting order parameter. The next-to-nearest neighbor hopping enhances superconductivity for h-doping, while diminishes it for e-doping. The charge-bond interaction alone leads to the opposite effect and, additionally, to the kinetic-energy gain upon condensation in the underdoped regime. With both terms included, with similar amplitudes, the height of the superconducting dome and the critical doping remain in favor of h-doping.

As a result, the superconducting gap exhibits nonstandard features including changed nodal directions. Our results also show that in the optimally doped regime the pure superconducting phase is typically unstable towards developing nematicity (breaking of the C4 symmetry). This has implications for the cuprate high-Tc superconductors, for which in this regime the so-called intertwined orders have recently been observed.

This approach allows for a systematic evaluation of the expectation values with full Gutzwiller wave function in finite-dimensional systems. It introduces results extending in an essential manner those obtained by means of the standard Gutzwiller approximation (GA), which is variationally exact only in infinite dimensions. Within the DE-GWF approach we discuss the principal paramagnetic properties and their relevance to heavy-fermion systems. We demonstrate the formation of an effective, narrow f band originating from atomic f-electron states and subsequently interpret this behavior as a direct itineracy of f electrons; it represents a combined effect of both the hybridization and the correlations induced by the Coulomb repulsive interaction. Such a feature is absent on the level of GA, which is equivalent to the zeroth order of our expansion. Formation of the hybridization- and electron-concentration-dependent narrow f band rationalizes the common assumption of such dispersion of f levels in the phenomenological modeling of the band structure of CeCoIn5. Moreover, it is shown that the emerging f-electron direct itineracy leads in a natural manner to three physically distinct regimes within a single model that are frequently discussed for 4f- or 5f-electron compounds as separate model situations. We identify these regimes as (i) the mixed-valence regime, (ii) Kondo/almost-Kondo insulating regime, and (iii) the Kondo-lattice limit when the f-electron occupancy is very close to the f-state half filling, ⟨nˆf⟩→1. The nonstandard features of the emerging correlated quantum liquid state are stressed."}],"citation":{"mla":"Wysokiński, Marcin, et al. “Gutzwiller Wave Function Solution for Anderson Lattice Model: Emerging Universal Regimes of Heavy Quasiparticle States.” <i>Physical Review B</i>, vol. 92, no. 12, 125135, American Physical Society, 2015, doi:<a href=\"https://doi.org/10.1103/PhysRevB.92.125135\">10.1103/PhysRevB.92.125135</a>.","apa":"Wysokiński, M., Kaczmarczyk, J., &#38; Spałek, J.
