Stroboscopic painting of optical potentials for atoms with subwavelength resolution
M. Lacki, P. Zoller, M. A Baranov
We propose and discuss a method to engineer stroboscopically arbitrary one-dimensional optical potentials with subwavelength resolution. Our approach is based on subwavelength opti…
Dynamical quantum phase transitions in collapse and revival oscillations of a quenched superfluid
Mateusz Lacki, Markus Heyl
In this work we revisit collapse and revival oscillations in superfluids suddenly quenched by strong local interactions for the case of a one-dimensional Bose-Hubbard model. As the…
Numerical studies of ground state fidelity of the Bose-Hubbard model
Mateusz Łacki, Bogdan Damski, Jakub Zakrzewski
We compute ground state fidelity of the one-dimensional Bose-Hubbard model at unit filling factor. To this aim, we apply the DMRG algorithm to systems with open and periodic bounda…
Extracting information from non adiabatic dynamics: excited symmetric states of the Bose-Hubbard model
M. Lacki, D. Delande, J. Zakrzewski
Using Fourier transform on a time series generated by unitary evolution, we extract many-body eigenstates of the Bose-Hubbard model corresponding to low energy excitations, which a…
Spin effects in Bose-Glass phases
Simone Paganelli, Mateusz Lacki, Veronica Ahufinger +2
We study the mechanism of formation of Bose glass (BG) phases in the spin-1 Bose Hubbard model when diagonal disorder is introduced. To this aim, we analyze first the phase diagram…
