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…
Electromagnetic shielding in quantum metrology
Yao Jin, Hongwei Yu
The dynamics of the quantum Fisher information of the parameters of the initial atomic state and atomic transition frequency is studied, in the framework of open quantum systems, f…
Dynamical behavior and geometric phase for a circularly accelerated two-level atom
Yao Jin, Jiawei Hu, Hongwei Yu
We study, in the framework of open quantum systems, the time evolution of a circularly accelerated two-level atom coupled in the multipolar scheme to a bath of fluctuating vacuum e…
