Nonhermitian adiabatic perturbation theory of topological quantization of the average velocity of a magnetic skyrmion under thermal fluctuations
Shan-Chang Tang, Yu Shi
We study the two-dimensional motion of a magnetic skyrmion driven by a ratchetlike polarized electric current that is periodic in both space and time. Some general cases are consid…
Accelerating Unruh-DeWitt detectors coupled with a spinor field
Dawei Wu, Shan-Chang Tang, Yu Shi
The behavior of accelerating Unruh-DeWitt detectors coupled with a spinor field in (3+1)-dimensional spacetime is investigated. For a single point-like detector with Gaussian switc…
Exact conditions for antiUnruh effect in (1+1)-dimensional spacetime
Dawei Wu, Ji-chong Yang, Yu Shi
Exact conditions for antiUnruh effect in (1+1)-dimensional spacetime are obtained. For detectors with Gaussian switching functions, the analytic results are similar to previous one…
Birth and death of entanglement between two accelerating Unruh-DeWitt detectors coupled with a scalar field
Dawei Wu, Shan-Chang Tang, Yu Shi
We consider two accelerating Unruh-DeWitt detectors coupled linearly or quadratically with a scalar field. We show that entanglement can be created by acceleration, and is divergen…
