Abstract
We investigate a quantum system consisting of two mirrors undergoing uniform acceleration in opposite directions and one or two stationary atoms localized in the right and left Rindler wedges, respectively. The system interacts with a scalar field described by plane-wave solutions in Rindler coordinates. We show that the combined effect of mirror-induced boundary conditions and the Unruh response leads to thermal factors together with spatial interference terms. In particular, the joint excitation probability exhibits enhancements beyond the product of individual probabilities, indicating field-mediated correlations across causally disconnected regions. These results provide insight into entanglement and decoherence in noninertial frames and are directly relevant to relativistic quantum information.
