Quantum phases of Bose-Bose mixtures on a triangular lattice
Liang He, Yongqiang Li, Ehud Altman +1
We investigate the zero temperature quantum phases of a Bose-Bose mixture on a triangular lattice using Bosonic Dynamical Mean Field Theory (BDMFT). We consider the case of total f…

Anisotropic pair-superfluidity of trapped two-component Bose gases
Yongqiang Li, Liang He, Walter Hofstetter
We theoretically investigate the pair-superfluid phase of two-component ultracold gases with negative inter-species interactions in an optical lattice. We establish the phase diagr…
