Thouless time analysis of Anderson and many-body localization transitions
Piotr Sierant, Dominique Delande, Jakub Zakrzewski
Spectral statistics of disordered systems encode Thouless and Heisenberg time scales whose ratio determines whether the system is chaotic or localized. Identifying similarities bet…
Confinement and lack of thermalization after quenches in the bosonic Schwinger model
Titas Chanda, Jakub Zakrzewski, Maciej Lewenstein +1
We excite the vacuum of a relativistic theory of bosons coupled to a gauge field in 1+1 dimensions (bosonic Schwinger model) out of equilibrium by creating a spatially separ…
Time dynamics with matrix product states: Many-body localization transition of large systems revisited
Titas Chanda, Piotr Sierant, Jakub Zakrzewski
We compare accuracy of two prime time evolution algorithms involving Matrix Product States - tDMRG (time-dependent density matrix renormalization group) and TDVP (time-dependent va…
Rescattering effects in streaking experiments of strong-field ionization
Michał Mandrysz, Matthias Kübel, Jakub Zakrzewski +1
Strong field ionization provides a unique mean to address complex dynamics of an electron in competing Coulomb and laser fields. Recent streak camera experiment (Kübel, et al., Phy…
Model of level statistics for disordered interacting quantum many-body systems
Piotr Sierant, Jakub Zakrzewski
We numerically study level statistics of disordered interacting quantum many-body systems. A two-parameter plasma model which controls level repulsion exponent and range of…
Double ionization of a three-electron atom: Spin correlation effects
Dmitry K. Efimov, Jakub S. Prauzner-Bechcicki, Jan H. Thiede +2
We study the effects of spin degrees of freedom and wave function symmetries on double ionization in three-electron systems. Each electron is assigned one spatial degree of freedom…
Energy level dynamics across the many-body localization transition
Artur Maksymov, Piotr Sierant, Jakub Zakrzewski
The level dynamics across the many body localization transition is examined for XXZ-spin model with a random magnetic field. We compare different scenaria of parameter dependent mo…
Many-body localization in presence of cavity mediated long-range interactions
Piotr Sierant, Krzysztof Biedroń, Giovanna Morigi +1
We show that a one-dimensional Hubbard model with all-to-all coupling may exhibit many-body localization in the presence of local disorder. We numerically identify the parameter sp…
