Probing Lorentz-invariance-violation with quantum coherence of Unruh-DeWitt detector
Yihao Wu, Xiaobao Liu, Zehua Tian
Testing Lorentz invariance violation (LIV) is notoriously difficult, as its characteristic energy scale, , in modified dispersion relations typically lies beyond current e…
Harvesting entanglement from the Lorentz-violating quantum field vacuum in a dipolar Bose-Einstein condensate
Zehua Tian, Weiping Yao, Xiaobao Liu +3
We theoretically propose an experimentally viable scheme to explore the transfer of nonclassical correlations from a dipolar Bose-Einstein condensate (BEC) to a pair of impurities…
Dissipation suppression for an Unruh-DeWitt battery with a reflecting boundary
Xiaobao Liu, Zehua Tian, Jiliang Jing
In the framework of open quantum systems, we study the dynamics of an accelerated quantum battery (QB), modeled as an Unruh-DeWitt detector interacting with a real massless scalar…
Dissipative dynamics of an open quantum battery in the BTZ spacetime
Zehua Tian, Xiaobao Liu, Jieci Wang +1
We consider how charging performances of a quantum battery, modeled as a two-level system, are influenced by the presence of vacuum fluctuations of a quantum field satisfying the D…
Entanglement dynamics in -deformed spacetime
Xiaobao Liu, Zehua Tian, Jiliang Jing
We treat two identical and mutually independent two-level atoms that are coupled to a quantum field as an open quantum system. The master equation that governs their evolution is d…
