Drag force of a exciton-polariton condensate under non-resonant pumping
Peisong He, Zhaoxin Liang
Exciton-polariton condensate in semiconductor microcavities constitute a novel kind of non-equilibrium superfluid. In a recent experiment [P. Stepanov, {\it et. al.,} Nat. Commun.…

An oscillating Casimir potential between two impurities in a spin-orbit coupled Bose-Einstein condensate
Pei-Song He, Qing Sun, An-Chun Ji
We study the Casimir potential between two impurities immersed in a spin-orbit coupled BoseEinstein condensate (BEC) with plane-wave order. We find that, by exchanging the virtual…

Casimir force between two impurities immersed in a Bose-Einstein condensate
Jian-Hua Liu, Yao-Hui Zhu, Pei-Song He
In this paper, we study the problem of an impurity with infinite mass and the Casimir force between two impurities immersed in a Bose-Einstein condensate. Our calculation results s…
