Gravity-induced accelerating expansion of excited-state Bose-Einstein condensate
Lijia Jiang, Jun-Hui Zheng
The Bose-Einstein condensate (BEC) of excited states, provides a different platform to explore the interplay between gravity and quantum physics. In this Letter, we study the respo…

Measuring the topological phase transition via the single-particle density matrix
Jun-Hui Zheng, Bernhard Irsigler, Lijia Jiang +2
We discuss the topological phase transition of the spin- fermionic Haldane model with repulsive on-site interaction. We show that the Berry curvature of the topologica…
