Energy Transport Induced by Transition from Weak to Strong Coupling Regime Between Non-Hermitian systems
I. V. Vovcenko, A. A. Zyablovsky, A. A. Pukhov +1
Recently, strong coupling between non-Hermitian physical systems of different nature is widely investigated due to it endows them with new properties. In this work, we investigate…
A new type of non-Hermitian phase transition in open systems far from thermal equilibrium
T. T. Sergeev, A. A. Zyablovsky, E. S. Andrianov +3
We demonstrate a new type of non-Hermitian phase transition in open systems far from thermal equilibrium, which takes place in coupled systems interacting with reservoirs at differ…
Dephasing-assisted entanglement in a system of strongly coupled qubits
I. V. Vovcenko, V. Yu. Shishkov, E. S. Andrianov
Creation of entangled states of quantum systems with low decoherence rates is a cornerstone in practical implementation of quantum computations. Processes of separate dephasing in…
Quantum theory of Rayleigh scattering
A. P. Vinogradov, V. Yu. Shishkov, I. V. Doronin +3
We develop a quantum theory of atomic Rayleigh scattering. Scattering is considered as a relaxation of incident photons from a selected mode of free space to the reservoir of the o…
Enhancement of the Raman Effect by Infrared Pumping
V. Yu. Shishkov, E. S. Andrianov, A. A. Pukhov +2
We propose a method for increasing the Raman scattering from an ensemble of molecules by up to four orders of magnitude. Our method requires an additional coherent source of IR rad…
Zeroth law of thermodynamics for thermalized open quantum systems having integrals of motion
V. Yu. Shishkov, E. S. Andrianov, A. A. Pukhov +2
We study the evolution of an open quantum system described by a dynamical semigroup having the Lindblad superoperator as a generator. This generator may have an eigenfunction with…
