A system of two-level atoms interacting with one mode of a quantized radiation field i\ considered by the quantum field theory. The existence of a phase transition to the spontaneous coherent state (SCS) is shown. This state arises from the Bose-Einstein condensation of the photons of the radiation

A master equation for population in a two-level system interacted with bosons in a timedependent electric field is derived in a noninteracting-blip approximation. For a \(\mathrm{cw}\) field the asymptotic solution of this equation is determined to all orders of the perturbation expansion with respe
This paper deals with a stochastic stability concept for discrete-time Markovian jump linear systems. The random jump parameter is associated to changes between the system operation modes due to failures or repairs, which can be well described by an underlying finite-state Markov chain. In the model
