Bose-Hubbard ladder subject to effective magnetic field: quench dynamics in a harmonic trap
Wladimir Tschischik, Roderich Moessner, Masudul Haque
Motivated by a recent experiment with optical lattices that has realized a ladder geometry with an effective magnetic field (Atala et al., Nature Physics \textbf{10}, 588 (2014)),…
Repulsive to attractive interaction quenches of 1D Bose gas in a harmonic trap
Wladimir Tschischik, Masudul Haque
We consider quantum quenches of harmonically trapped one-dimensional bosons from repulsive to attractive interactions, and the resulting breathing dynamics of the so-called `super-…
Breathing mode in the Bose-Hubbard chain with a harmonic trapping potential
Wladimir Tschischik, Roderich Moessner, Masudul Haque
We investigate the breathing mode of harmonically trapped bosons in an optical lattice at small site occupancies. The Bose-Hubbard model with a trapping potential is used to descri…
Non-equilibrium dynamics in Bose-Hubbard ladders
Wladimir Tschischik, Masudul Haque, Roderich Moessner
Motivated by a recent experiment on the non-equilibrium dynamics of interacting bosons in ladder-shaped optical lattices, we report exact calculations on the sweep dynamics of Bose…
