Berry Curvature of interacting bosons in a honeycomb lattice
Yun Li, Pinaki Sengupta, George G. Batrouni +2
We consider soft-core bosons with onsite interaction loaded in the honeycomb lattice with different site energies for the two sublattices. Using both a mean-field approach and quan…

Collective modes of a harmonically trapped one-dimensional Bose gas: the effects of finite particle number and nonzero temperature
Xiao-Long Chen, Yun Li, Hui Hu
Following the idea of the density functional approach, we develop a generalized Bogoliubov theory of an interacting Bose gas confined in a one-dimensional harmonic trap, by using a…
