Supersolid phases of ultracold bosons trapped in optical lattices dressed with Rydberg -states
Mathieu Barbier, Henrik Lütjeharms, Walter Hofstetter
Engineering quantum phases with spontaneously broken symmetries is a major goal of research in different fields. Trapped ultracold Rydberg-excited atoms in optical lattices are a p…
Extended Bose-Hubbard models with Rydberg macrodimer dressing
Mathieu Barbier, Simon Hollerith, Walter Hofstetter
Extended Hubbard models have proven to bear novel quantum states, but their experimental realization remains challenging. In this work we propose to use bosonic quantum gases dress…
Topological Mott transition in a Weyl-Hubbard model with dynamical mean-field theory
Bernhard Irsigler, Tobias Grass, Jun-Hui Zheng +2
Weyl semimetals are three-dimensional, topologically protected, gapless phases which show exotic phenomena such as Fermi arc surface states or negative magnetoresistance. It is an…
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…
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…
