Slow dynamics and non-ergodicity of the bosonic quantum East model in the semiclassical limit
Andreas Geißler, Juan P. Garrahan
We study the unitary dynamics of the bosonic quantum East model, a kinetically constrained lattice model which generalises the quantum East model to arbitrary occupation per site.…
Finite-size scaling analysis of localization transitions in the disordered two-dimensional Bose-Hubbard model within the fluctuation operator expansion method
Andreas Geißler
The disordered Bose-Hubbard model in two dimensions at non-integer filling admits a superfluid to Bose-glass transition at weak disorder. Less understood are the properties of this…
Mobility edge of the two dimensional Bose-Hubbard model
Andreas Geißler, Guido Pupillo
We analyze the disorder driven localization of the two dimensional Bose-Hubbard model by evaluating the full low energy quasiparticle spectrum via a recently developed fluctuation…
Supersolid phases of Rydberg-excited bosons on a triangular lattice
Jaromir Panas, Mathieu Barbier, Andreas Geißler +1
Recent experiments with ultracold Rydberg-excited atoms have shown that long-range interactions can give rise to spatially ordered structures. Observation of crystalline phases in…
Density-wave steady-state phase of dissipative ultracold fermions with nearest-neighbor interactions
Jaromir Panas, Michael Pasek, Arya Dhar +6
In this work we investigate the effect of local dissipation on the presence of density-wave ordering in spinful fermions with both local and nearest-neighbor interactions as descri…
Decay-dephasing-induced steady states in bosonic Rydberg-excited quantum gases in an optical lattice
Mathieu Barbier, Andreas Geißler, Walter Hofstetter
We investigate the possibility of realizing supersolid quantum phases in bosonic Rydberg-excited quantum lattice gases in the presence of non-unitary processes, by simulating the d…
