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…

Doublon-holon binding as origin of Mott transition and fractionalized spin liquid -- Asymptotic solution of the Hubbard model in the limit of large coordination
Sen Zhou, Long Liang, Ziqiang Wang
An analytical solution of the Mott transition is obtained for the Hubbard model on the Bethe lattice in the large coordination number () limit. The excitonic binding of doublons…
