Inter-state switching in stochastic gene expression: Exact solution, an adiabatic limit and oscillations in molecular distributions
K. G. Petrosyan
We consider the stochastic gene expression process with inter-state flip-flops. An exact steady-state solution to the master equation is calculated. One of the main goals in this p…
Physics of Cold Atomic Fermi Gases
E. A. Ayryan, K. G. Petrosyan, A. H. Gevorgyan +2
We consider a cold two-species atomic Fermi gas confined in a trap. We combine the Hermitian coupling between the states (we assume them to be the states with different spins) with…
Electrons for Detection of Casimir Photons
Edik A. Ayryan, Karen G. Petrosyan, Ashot H. Gevorgyan +2
We propose a method for the detection of a dynamical Casimir effect. Assuming that the Casimir photons are being generated in an electromagnetic cavity with a vibrating wall (dynam…
X-Ray Radiation Generation in Heat Engines Using Electron Cooling
E. A. Ayryan, M. Hnatic, K. G. Petrosyan +3
We consider a relativistic quantum heat engine that goes through a thermodynamical cycle consisting of stages involving laser-assisted cooling of electrons and the generation of Xr…
Non-equilibrium Lyapunov function and a fluctuation relation for stochastic systems: Poisson representation approach
K. G. Petrosyan, Chin-Kun Hu
We present a statistical physics framework for description of nonlinear non-equilibrium stochastic processes, modeled via chemical master equation, in the weak-noise limit. Using t…
Effect of time delay on the onset of synchronization of the stochastic Kuramoto model
Monoj Kumar Sen, Bidhan Chandra Bag, Karen G. Petrosyan +1
We consider the Kuramoto model of globally coupled phase oscillators with time-delayed interactions, that is subject to the Ornstein-Uhlenbeck (Gaussian) colored or the non-Gaussia…
