Dissipative dynamics of the semiconductor-cavity QED with q-deformed bosons in the dispersive approximation

Abstract

In this paper we give fully analytical description of the dynamics of a collection of $N$-Frenkel excitons in high density regime dispersively coupled to a single mode cavity field, in the presence of both exciton and cavity-field dissipations. By using excitonic operators as q-deformed bosonic operators for the system, we solve analytically the Liouville equation for the density operator at zero temperature and investigate the influence of the number of excitons and the effect of both dissipations on dynamical behavior of the system. We use the solution of master equation to explore the dissipative dynamics of non-classical properties such as, molecule-field entanglement, quadrature squeezing of the field, and molecular dipole squeezing. We find that the non-classical properties are strongly affected by the number of excitons and also by the existence of both dissipations.
