Frustration and time reversal symmetry breaking for Fermi and Bose-Fermi systems
Krzysztof Sacha, Katarzyna Targonska, Jakub Zakrzewski
The modulation of an optical lattice potential that breaks time-reversal symmetry enables the realization of complex tunneling amplitudes in the corresponding tight-binding model.…
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…
Dipolar bosons on an optical lattice ring
Michal Maik, Pierfrancesco Buonsante, Alessandro Vezzani +1
We consider an ultra-small system of polarized bosons on an optical lattice with a ring topology interacting via long range dipole-dipole interactions. Dipoles polarized perpendicu…
Numerical Computation of Dynamically Important Excited States of Many-Body Systems
Mateusz Lacki, Dominique Delande, Jakub Zakrzewski
We present an extension of the time-dependent Density Matrix Renormalization Group (t-DMRG), also known as Time Evolving Block Decimation algorithm (TEBD), allowing for the computa…
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…
Tunable dipolar resonances and Einstein-de Haas effect in a Rb-87 atoms condensate
Tomasz Swislocki, Tomasz Sowinski, Joanna Pietraszewicz +4
We study a spinor condensate of Rb-87 atoms in F = 1 hyperfine state confined in an optical dipole trap. Putting initially all atoms in mF = 1 component we observe a significant tr…
