چکیده

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.

Proposal to produce long-lived mesoscopic superpositions through an atom-driven field interaction

The mastery of techniques for preparing cavity-field states through atom-field interaction in cavity quantum electrodynamics (QED) is crucial to many useful applications in quantum optics. As high-Q cavities have permitted the preparation of cavity-field superpositions of the form |Ψ〉 = ∣α eiφ 〉 + ∣α e−iφ 〉) / √ 2, with mean number of oscillator quanta |α| ≈ 10, mesoscopic quantum coherence in ...

Finite temperature correlation function of two dissipative massive scalar fields: Thermofield approach

The present paper aims at investigating the manner of two dissipative massive scalar fields. Two massive scalar fields that interact with a reservoir were considered and a reservoir was modeled by continuum Klein-Gordon fields. The Lagrangian of the total system was canonically quantized and the dynamics of the system was determined using the Euler-Lagrange equation. Then, the explicit form of the...

We consider a massless scalar field in 1+1 dimensions that satisfies a Robin boundary condition at a non-relativistic moving boundary. Using the perturbative approach introduced by Ford and Vilenkin, we compute the total force on the moving boundary. In contrast to what happens for the Dirichlet and Neumann boundary conditions, in addition to a dissipative part, the force acquires also a disper...
