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…
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…
Optimal estimation of parameters for scalar fields in expanding universe exhibiting Lorentz invariance violation
Xiaobao Liu, Zehua Tian, Jieci Wang +1
We address the optimal estimation of quantum parameters, in the framework of local quantum estimation theory, for a massive scalar quantum field in the expanding Robertson-Walker u…
