Influence of Virtual Photon Process on the Generation of Squeezed Light from Atoms in an Optical Cavity

چکیده
We show that a collection of two-level atoms in an optical cavity beyond the rotating wave approximation and in the dispersive-adiabatic and non-dispersive adiabatic regime constitutes a nonlinear medium and is capable of generating squeezed state of light. It is found that squeezing produced in the non-dispersive adiabatic regime is significantly high compared to that produced in the dispersive-adiabatic limit. On the other hand, we also show that it could be possible to observe the Dicke superradiant quantum phase transition in the dispersive-adiabatic regime where the ~ A term is negligible. Such a system can be an essential component of a larger quantum-communication system.

Quantum Squeezed Light Propagation in an Optical Parity-Time (PT)-Symmetric Structure
We investigate the medium effect of a parity-time (PT)-symmetric bilayer on the quantum optical properties of an incident squeezed light at zero temperature (T=0 K). To do so, we use the canonical quantization approach and describe the amplification and dissipation properties of the constituent layers of the bilayer structure by Lorentz model to analyze the quadrature squeezing of the outgoing ...
متن کاملGeneralized master equation for systems in nonideal cavities with squeezed baths
The master equation for the density operator of a system in a lossy cavity, which is coupled to a squeezed bath, is generalized so as to include the effects of an enhanced loss through a mirror of finite transmittivity. As compared to the standard master equation, which is valid for a nearly-perfect cavity, the generalized master equation is found to contain additional terms that account for an...
متن کاملActive optical frequency standard using sequential coupling of atomic ensembles
Recently, several theoretical proposals addressed the generation of an active optical frequency standard based on atomic ensembles trapped in an optical lattice potential inside an optical resonator. Using atoms with a narrow linewidth transition and population inversion together with a “bad” cavity allows us to realize the super-radiant photon emission regime. These schemes reduce the influenc...
متن کاملSqueezing spectrum for radiation of atoms in two laser fields
Over the past few years, properties of nonclassical states o f light as well as different methods for their production have been widely discussed. In most works, both theoretical and experimental ones, monochromatic continuous-wave pump fields are considered to obtain the nonclassical light, including squeezed states [ 1 ]. Several papers are also devoted to problems of squeezed light pulses [ ...
متن کاملGenerating controllable atom-light entanglement with a Raman atom laser system.
We introduce a scheme for creating continuous variable entanglement between an atomic beam and an optical field, by using squeezed light to outcouple atoms from a Bose-Einstein condensate via a Raman transition. We model the full multimode dynamics of the atom laser beam and the squeezed optical field and show that, with appropriate two-photon detuning and two-photon Rabi frequency, the transmi...
