Position-dependent thermalization of two-level probes in de Sitter spacetime: Interplay between Gibbons-Hawking and Unruh effects
Yao Jin
We investigate the thermalization process of two-level probes in de Sitter spacetime from a quantum-metrological perspective. For a static probe separated by a finite distance from…

Optimal Quantum Metrology for Probing the Unruh Effect with Uniformly Accelerated Two-Level Atoms
Yao Jin
We develop a quantum metrological framework for optimizing the probing of the Unruh effect using uniformly accelerated two-level atomic probes. The acceleration-dependent factor ge…

Optimal estimation of quantum boundary effect in cosmic string space-time
Yao Jin
The presence of a cosmic string modifies vacuum fluctuations, making the evolution of a two-level polarizable atom position dependent. Such modifications produce effects on the ato…
