Fluctuations of topological charges in two-dimensional classical Heisenberg model through high-temperature and low-temperature expansions
Shan-Chang Tang
It is well known that KT transition in 2d XY model is driven by the binding and unbinding of topological defects, which can be characterized by the fluctuation of topological charg…
Fluctuations of topological charges in two-dimensional classical Heisenberg model
Shan-Chang Tang, Yu Shi
Binding and unbinding of vortices drives Kosterlitz-Thouless phase transition in two-dimensional XY model. Here we investigate whether similar mechanism works in two-dimensional He…
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…
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…
