Geometric phase for an accelerated two-level atom in AdS spacetime
Linghui Qiu, Jialin Zhang, Hongwei Yu
We have investigated the geometric phase acquired by a uniformly accelerated Unruh-DeWitt detector coupled to vacuum fluctuations of a massless conformal scalar field in anti-de Si…

Entanglement harvesting in cosmic string spacetime
Ying Ji, Jialin Zhang, Hongwei Yu
We investigate the entanglement harvesting phenomenon for static detectors that locally interact with massless scalar fields in the cosmic string spacetime, which, though locally f…
