Analytical operator solution of master equations describing phase-sensitive processes
We present a method of solving master equations which may describe, in their
most general form, phase sensitive processes such as decay and amplification.
We make use of the superoperator technique.Comment: 10 pages, LaTex, 3 figures, accepted for publication in International

Atomic Inversion and Entanglement Dynamics for Squeezed Coherent Thermal States in the Jaynes-Cummings Model
The tussling interplay between the thermal photons and the squeezed photons
is discussed. The `classical noise' is represented by the thermal photons and
the `quantum noise' is represented by the squeezed photons, which are pitted
against each other in the background of a coherent field (represented by the
coherent photons). The photon counting distribution (PCD) corresponding to the
squeezed coherent thermal states are employed for this purpose. It is observed
that the addition of thermal photons and squeezed photons have counterbalancing
effects, by delocalizing and localizing the PCD, respectively. Various aspects
of the atom-field interaction, like the atomic inversion, entanglement dynamics
in the Jaynes-Cummings model have been investigated. Particular attention is
given to the study of atomic inversion and entanglement dynamics due to the
addition of thermal and squeezed photons to the coherent state. The interplay
of thermal photons and squeezed photons have drastic effects on the PCD, atomic
inversion and entanglement dynamics of the atom-field interaction.Comment: This research article contains 10 pages and 15 figure
