Second-law-allowed temporal cooling of the coldest reservoir without external refrigeration
I. V. Vovchenko, A. A. Zyablovsky, A. A. Pukhov +1
Non-equilibrium quantum thermodynamics is an intensively developing field with many existing applications. We study the dynamics of temperatures and chemical potentials of fermioni…
Anomalous dependence of sensitivity on observation time caused by memory retention in the time crystal
T. T. Sergeev, A. A. Zyablovsky, E. S. Andrianov
In this work, we consider a composite atom-cavity system interacting with a ring resonator. In such a structure, time crystal regime can be observed. We show that a quadratic obser…
Spontaneous PT-symmetry breaking transitions under the influence of noise in an optomechanical system
A. R. Mukhamedyanov, E. S. Andrianov, A. A. Zyablovsky
Spontaneous symmetry breaking is a phenomenon of an alteration of a state symmetry without a change in the system symmetry. A transition from a state with unbroken symmetry to a st…
Non-monotonic dependence of the radiation linewidth in a phonon laser
A. R. Mukhamedyanov, E. S. Andrianov, A. A. Zyablovsky
A phonon laser is an important device that can generate coherent sound waves at gigahertz frequency. In this paper, we demonstrate that in a phonon laser, the radiation line width…
