Radiative process of two entangled uniformly accelerated atoms in a thermal bath: a possible case of anti-Unruh event

A bstract We study the radiative process of two entangled two-level atoms uniformly accelerated in a thermal bath, coupled to massless scalar field. First, by using positive frequency Wightman function from Minkowski modes with Rindler transformation we provide transition probabilities for transitions maximally symmetric and anti-symmetric Bell states collective excited or ground state (1 + 1) 3) dimensions. observe possible case anti-Unruh-like event these probabilities, though (1+1) (1+3) dimensional results are not completely equivalent. infer that bath plays major role occurrence effect, as it is also present corresponding single detector this case. Second, have considered Green’s functions terms vacuum Unruh estimating same. Here anti-Unruh effect appears only state. It noticed here equivalent, detector, do any effect. This suggests entanglement between main cause observed In going through investigation, find probability under interchange bath’s temperature mode analysis; whereas mode. further comment on whether observation may shed light analogy an observer real bath. An elaborate investigation classifications our effects, i.e., either weak strong thoroughly demonstrated.
