Non-equilibrium dissipative stabilization of s- and d-wave superconductivity
Aleksey Lunkin, Yury Holubeu, Denis Golež +1
Stabilizing superconductivity beyond its equilibrium regime has been one of the quests of nonequilibrium state engineering. We report the presence of nonthermal pairing gap in BCS…
A Hubbard exciton fluid in a photo-doped antiferromagnetic Mott insulator
Omar Mehio, Xinwei Li, Honglie Ning +7
The undoped antiferromagnetic Mott insulator naturally has one charge carrier per lattice site. When it is doped with additional carriers, they are unstable to spin fluctuation-med…
Floquet engineering of binding in doped and photo-doped Mott insulators
Madhumita Sarkar, Zala Lenarčič, Denis Golež
We investigate the emergence of bound states in chemically and photo-doped Mott insulators, mediated by spin and -pairing fluctuations within both 2-leg ladder and 2D systems. T…
Emergent dipole moment conservation and subdiffusion in tilted chains
S. Nandy, J. Herbrych, Z. Lenarčič +3
We study the transport dynamics of an interacting tilted (Stark) chain. We show that the crossover between diffusive and subdiffusive dynamics is governed by , where …
Spin diffusion in perturbed isotropic Heisenberg spin chain
S. Nandy, Z. Lenarčič, E. Ilievski +3
The isotropic Heisenberg chain represents a particular case of an integrable many-body system exhibiting superdiffusive spin transport at finite temperatures. Here, we show that th…
From dissipationless to normal diffusion in easy-axis Heisenberg spin chain
P. Prelovšek, S. Nandy, Z. Lenarčič +2
The anomalous spin diffusion of the integrable easy-axis Heisenberg chain originates in the ballistic transport of symmetry sectors with nonzero magnetization. Ballistic transport…
Critical behavior near the many-body localization transition in driven open systems
Zala Lenarčič, Ori Alberton, Achim Rosch +1
Coupling a many-body localized system to a thermal bath breaks local conservation laws and washes out signatures of localization. When the bath is non-thermal or when the system is…
Activating many-body localization in solids by driving with light
Zala Lenarčič, Ehud Altman, Achim Rosch
Due to the presence of phonons, many body localization (MBL) does not occur in disordered solids, even if disorder is strong. Local conservation laws characterizing an underlying M…
Time-dependent generalized Gibbs ensembles in open quantum systems
Florian Lange, Zala Lenarčič, Achim Rosch
Generalized Gibbs ensembles have been used as powerful tools to describe the steady state of integrable many-particle quantum systems after a sudden change of the Hamiltonian. Here…
Pumping approximately integrable systems
Florian Lange, Zala Lenarčič, Achim Rosch
Weak perturbations can drive an interacting many-particle system far from its initial equilibrium state if one is able to pump into degrees of freedom approximately protected by co…
Exciton Recombination in One-Dimensional Organic Mott Insulators
Zala Lenarčič, Martin Eckstein, Peter Prelovšek
We present a theory for the recombination of (charged) holons and doublons in one-dimensional organic Mott insulators, which is responsible for the decay of a photoexcited metallic…
Holon-Doublon Binding as the Mechanism for the Mott transition
Peter Prelovšek, Jure Kokalj, Zala Lenarčič +1
We study the binding of a holon to a doublon in a half-filled Hubbard model as the mechanism of the zero-temperature metal-insulator transition. In a spin polarized system and a no…
Exact asymptotics of the current in boundary dissipated quantum chains in large external fields
Zala Lenarčič, Tomaž Prosen
Boundary driven quantum master equation for a general inhomogeneous (non-integrable) anisotropic Heisenberg spin chain, or an equivalent nearest neighbor interacting spinless…
Charge Recombination in Undoped Cuprates
Zala Lenarčič, Peter Prelovšek
We theoretically analyse the process of charge recombination in the planar Mott-Hubbard insulators with the aim to explain short picosecond-range lifetime of photoexcited carriers,…
Unusual Two-stage Dynamics of the Spin-Lattice Polaron Formation
Jan Kogoj, Zala Lenarcic, Denis Golez +3
We follow the formation of a spin-lattice polaron after a quantum quench that simulates absorption of the pump{pulse in the time-resolved experiments. We discover a two-stage relax…
Optical response of highly excited particles in a strongly correlated system
Zala Lenarčič, Denis Golež, Janez Bonča +1
We present a linear-response formalism for a system of correlated electrons out of equilibrium, as relevant for the probe optical absorption in pump-probe experiments. We consider…
Ultrafast charge recombination in photoexcited Mott-Hubbard insulator
Zala Lenarčič, Peter Prelovšek
We present a calculation of the recombination rate of the excited holon-doublon pairs based on the two-dimensional model relevant for undoped cuprates which shows that fast process…
Dielectric breakdown in spin polarized Mott insulator
Zala Lenarčič, Peter Prelovšek
Nonlinear response of a Mott insulator to external electric field, corresponding to dielectric breakdown phenomenon, is studied within of a one-dimensional half-filled Hubbard mode…
