Quadrature squeezing and information entropy squeezing in nonlinear two-level spin models
(World Scientific, 2010-04)
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 ...
Atomic entropy squeezing in three-level systems
(Springer, 2014-02)
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 ...
Variance squeezing and information entropy squeezing via Bloch coherent states in two-level nonlinear spin models
(Elsevier Gmbh, 2014-10)
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 ...
Information entropy and spin-squeezing in atomic three-level systems
(World Scientific, 2013-07)
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 ...
Planar quantum squeezing in spin-1/2 systems
(IOP Publishing, 2015-10)
Planar quantum squeezed (PQS) states, i.e. quantum states which are squeezed in two orthogonal spin components on a plane, have recently attracted attention due to their applications in atomic interferometry and quantum ...
Generation of decoherence-free displaced squeezed states of radiation fields and a squeezed reservoir for atoms in cavity qed
(AMERICAN PHYSICAL SOCIETY, 2008)
MECÁNICA CUÁNTICA DE LOS ESTADOS COHERENTES Y COMPRIMIDOS
(2010-12-02)
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 ...
A time-dependent pseudo-Hermitian Hamiltonian for a cavity mode with pure imaginary frequency
(2021-11-01)
In this work we first present a general treatment for a time-dependent (TD) pseudo-Hermitian quadratic Hamiltonian, considering an equally TD and non-Hermitian Dyson map. Then we particularize our study to a TD pseudo-Hermitian ...
