The nonclassical squeezing effect emerging from a nonlinear coupling model (generalized Jaynes–Cummings model) of a two-level atom interacting resonantly with a bimodal cavity field via two-photon transitions is investigated ...

Normal squeezing, variance and entropy squeezing factors based on the Heisenberg uncertainty principle and Shannon information entropy theory, respectively, derived from the entangled states of two-mode coherent states in ...

We formally developed the theory of coherent and squeezed states for the harmonic oscillator. This was based on the Weyl operator (related to the Heisenberg – Weyl group 1 ), and squeezing operator (related ...

It is shown that q-deformed Coherent Spin States (CSS), belonging to the SUq(2) representation, behave as Intelligent Spin States (ISS). The proof is based on the calculation of spin-squeezing observables, for both CSS and ISS.

We consider the problem of an atomic three-level system (in a ladder configuration) interacting with a radiation field. Assuming a coherent state as the initial state, we solve exactly the time evolution of the system. We ...

We briefly discuss four different possible types of transitions from quark to hadronic matter and their characteristic signatures in terms of correlations. We also highlight the effects arising from mass modification of ...

We consider the problem of an atomic three-level system in interaction with a radiation field. The time evolution of the system, in atomic ladder and Λ configurations, is solved exactly assuming a coherent-state as the ...
