Coexistence of localized and extended phases: Many-body localization in a harmonic trap
Titas Chanda, Ruixiao Yao, Jakub Zakrzewski
We show that the presence of a harmonic trap may in itself lead to many-body localization for cold atoms confined in that trap in a quasi-one-dimensional geometry. Specifically, th…
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…
Accurate determination of the superfluid-insulator transition in the one-dimensional Bose-Hubbard model
Jakub Zakrzewski, Dominique Delande
The quantum phase transition point between the insulator and the superfluid phase at unit filling factor of the infinite one-dimensional Bose-Hubbard model is numerically computed…
Collective excitation of trapped degenerate Fermi gases
Bogdan Damski, Krzysztof Sacha, Jakub Zakrzewski
We show that the slow driving of a focused laser beam through the cloud of trapped cold fermions allows for a creation of the collective excitation in the system. The method, propo…
