Physical Review D - Particles, Fields, Gravitation and Cosmology, 94(6), [065010]. DOI: 10.1103/PhysRevD.94.065010http://nur.nu.edu.kz/handle/123456789/2207An exact correspondence between a black hole and an accelerating mirror is demonstrated. It is shown that for a massless minimally coupled scalar field, the same Bogolubov coefficients connecting the "in" and "out" states occur for a (1+1)-dimensional flat spacetime with a particular perfectly reflecting accelerating boundary trajectory and a (1+1)-dimensional curved spacetime in which a null shell collapses to form a black hole. Generalization of the latter to the (3+1)-dimensional case is discussed. The spectral dynamics is computed in both (1+1)-dimensional spacetimes along with the energy flux in the spacetime with a mirror. It is shown that the approach to equilibrium is monotonic, asymmetric in terms of the rate, and there is a specific time which characterizes the system when it is the most out of equilibrium.enAttribution-NonCommercial-ShareAlike 3.0 United Statesblack holemirrorspace-timeArticle
