The Unruh effect and its applications
It has been 30 years since the discovery of the Unruh effect. It has played a crucial role in
our understanding that the particle content of a field theory is observer dependent. This …

Geometric phase for an accelerated two-level atom and the Unruh effect
J Hu, H Yu - Physical Review A—Atomic, Molecular, and Optical …, 2012 - APS
We study, in the framework of open quantum systems, the geometric phase acquired by a
uniformly accelerated two-level atom undergoing nonunitary evolution due to its coupling to …

Quantum electrodynamics of accelerated atoms in free space and in cavities
We consider a gedanken experiment with a beam of atoms in their ground state that are
accelerated through a single-mode cavity. We show that taking into account of the …

Spontaneous excitation of an accelerated atom in a spacetime with a reflecting plane boundary
H Yu, S Lu - Physical Review D—Particles, Fields, Gravitation, and …, 2005 - APS
We study a two-level atom in interaction with a real massless scalar quantum field in a
spacetime with a reflecting boundary. The presence of the boundary modifies the quantum …
