Quantum evolution of mixed states and performance of quantum heat engines
Anatoly A. Svidzinsky, Wenzhuo Zhang
We introduce a technique for calculating the density operator time evolution along the lines of Heisenberg representation of quantum mechanics. Using this technique, we find the ex…
Dicke States for Accelerated Two Two-Level Atoms
Muzzamal I. Shaukat, Charles A. Wallace, Anatoly A. Svidzinsky +1
We explore the formation of Dicke states. A system consisting of two two-level atoms located in the right Rindler wedge, has investigated to determine the conditions under which th…
Black-hole powered quantum coherent amplifier
Avijit Misra, Pritam Chattopadhyay, Anatoly Svidzinsky +2
Atoms falling into a black hole (BH) through a cavity are shown to enable coherent amplification of light quanta powered by the BH gravitational vacuum energy. This process can har…
Minkowski vacuum entanglement and accelerated oscillator chains
Anatoly A. Svidzinsky, Marlan O. Scully, William Unruh
Minkowski vacuum is empty from the perspective of Unruh-Minkowski photons, however, in the Rindler picture, it is filled with entangled pairs of Rindler photons. A ground-state ato…
