Strong-Coupling Phases of Frustrated Bosons on a 2-leg Ladder with Ring Exchange
D. N. Sheng, Olexei I. Motrunich, Simon Trebst +2
Developing a theoretical framework to access quantum phases of itinerant bosons or fermions in two dimensions (2D) that exhibit singular structure along surfaces in momentum space…

Supersolid Order from Disorder: Hard-Core Bosons on the Triangular Lattice
R. G. Melko, A. Paramekanti, A. A. Burkov +3
We study the interplay of Mott localization, geometric frustration, and superfluidity for hard-core bosons with nearest-neighbor repulsion on the triangular lattice. For this model…
