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…
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…
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…
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…
