Reliable quantum master equation of the Unruh-DeWitt detector
Si-Wei Han, Wenjing Chen, Langxuan Chen +2
In this paper, we present a method for estimating the validity range of the quantum Markovian master equation as applied to the Unruh-DeWitt (UDW) detector within a broader context…

Quantum Fisher information of a cosmic qubit undergoing non-Markovian de Sitter evolution
Langxuan Chen, Jun Feng
We revisit the problem of thermalization process for an Unruh-DeWitt (UDW) detector in de Sitter space. We derive the full dynamics of the detector in the context of open quantum s…
