Band geometry, Berry curvature and superfluid weight
Long Liang, Tuomas I. Vanhala, Sebastiano Peotta +3
We present a theory of the superfluid weight in multiband attractive Hubbard models within the Bardeen-Cooper-Schrieffer (BCS) mean field framework. We show how to separate the geo…

Global Phase Diagram of the Extended Kitaev-Heisenberg Model on Honeycomb Lattice
Jie Lou, Long Liang, Yue Yu +1
We study the extended Kitaev-Heisenberg (EKH) quantum spin model by adding bond-dependent off-diagonal Heisenberg term into the original KH model, which was recently proposed to de…

Collective modes in a Dirac insulator with short range interactions
Xi Luo, Yue Yu, Long Liang
We study a Haldane model with nearest neighbor interactions. We find one-dimensional like collective modes arising due to the interplay of pseudo-spin and valley degrees of freedom…
