Hilbert space shattering and disorder-free localization in polar lattice gases
Wei-Han Li, Xiaolong Deng, Luis Santos
Emerging dynamical constraints resulting from inter-site interactions severely limit particle mobility in polar lattice gases. Whereas in absence of disorder hard-core Hubbard mode…
Cluster dynamics in two-dimensional lattice gases with inter-site interactions
Wei-Han Li, Arya Dhar, Xiaolong Deng +1
Sufficiently strong inter-site interactions in extended-Hubbard and XXZ spin models result in dynamically-bound clusters at neighboring sites. We show that the dynamics of these cl…
Topological transitions of interacting bosons in one-dimensional bi-chromatic optical lattices
Xiaolong Deng, Luis Santos
Ultra-cold atoms in 1D bi-chromatic lattices constitute a surprisingly simple system for the study of topological insulators. We show that topological phase transitions constitute…
Bosonization and entanglement spectrum for one-dimensional polar bosons on disordered lattices
X. Deng, R. Citro, E. Orignac +2
The extended Bose-Hubbard model subjected to a disordered potential is predicted to display a rich phase diagram. In the case of uniform random disorder one finds two insulating qu…
Ultracold Lattice Gases with Periodically Modulated Interactions
Akos Rapp, Xiaolong Deng, Luis Santos
We show that a time-dependent magnetic field inducing a periodically modulated scattering length may lead to interesting novel scenarios for cold gases in optical lattices, charact…
Polar bosons in one-dimensional disordered optical lattices
Xiaolong Deng, Roberta Citro, Edmond Orignac +2
We analyze the effects of disorder and quasi-disorder on the ground-state properties of ultra-cold polar bosons in optical lattices. We show that the interplay between disorder and…
