Bricks that every removable edge is solitary
Jinxin Xue, Jun Ge, Fuliang Lu +1
A brick is a 3-connected graph such that has a perfect matching for any two distinct vertices . An edge in a matching covered graph is removable if…

Density instabilities and thermal stabilization of phase separated states in dipolar lattice bosons
Yaghmorassene Hebib, Stefano Peaquin, Chao Zhang +2
Recent advances in realizing nearly degenerate dipolar gases in optical lattices have enabled the study of quantum systems with long-range anisotropic interactions. Here, we invest…

Floquet-tuned superfluid-checkerboard competition in dipolar bosons
Jin Yang, Yaghmorassene Hebib, Chao Zhang
We study hard-core dipolar bosons on a square lattice subject to a unidirectional periodic drive that Floquet-engineers anisotropic hopping. Driving along one lattice direction pro…
