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…
Paging with Succinct Predictions
Antonios Antoniadis, Joan Boyar, Marek Eliáš +5
Paging is a prototypical problem in the area of online algorithms. It has also played a central role in the development of learning-augmented algorithms -- a recent line of researc…
Does relativistic motion always degrade quantum Fisher information?
Xiaobao Liu, Jiliang Jing, Zehua Tian +1
We investigate the ultimate estimation precision, characterized by the quantum Fisher information, of a two-level atom as a detector which is coupled to massless scalar field in th…
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…

We study, in the paradigm of open quantum systems, the dynamics of quantum coherence of a static polarizable two-level atom which is coupled with a thermal bath of fluctuating elec…
Protecting quantum coherence of two-level atoms from vacuum fluctuations of electromagnetic field
Xiaobao Liu, Zehua Tian, Jieci Wang +1
In the framework of open quantum systems, we study the dynamics of a static polarizable two-level atom interacting with a bath of fluctuating vacuum electromagnetic field and explo…
