Quantum Mpemba-like effect in Unruh thermalization
Zihao Wang, Wenjing Chen, Si-Wei Han +4
We revisit the thermal nature of the Unruh effect within a quantum thermodynamic framework. For a Unruh-deWitt (UDW) detector in -dimensional Minkowski spacetime, we demonstrate…
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…
Work extraction from long-lived quantum coherence of a three-level system
Wenjing Chen, Si-Wei Han, Xiaoshan Feng +1
We analyze work extraction protocols using the long-lived quantum coherence of a three-level quantum system, which is coupled to a thermal bath through dipole-monopole interactions…
Quantum thermodynamics in a rotating BTZ black hole spacetime
Wenjing Chen, Yixuan Ma, Si-Wei Han +2
We address the problem of the thermalization process for an Unruh-DeWitt (UDW) detector outside a BTZ black hole, from a perspective of quantum thermodynamics. In the context of an…
