ENTROPY FOR THE THREE-LEVEL ONE-MODE JAYNES–CUMMINGS MODEL

E.I. Aliskenderov, TRUNG DUNG HO

Abstract

The evolution of the atomic (field) entropy is calculated for the three-level one-mode Jaynes–Cummings model. Numerical calculations are performed for various values of atom–field coupling constants and the evolution of the entropy is compared with the corresponding evolutions of the mean photon number and level occupation probabilities.

Evolution of the entropy of light field interacting with the V-type three-level atom via intensity-dependent coupling

Huang Chun-Jia, He Hui-Yong, Kong Fan-Zhi +2 more

The evolution properties of the entropy of a single-mode light field interacting with the V-type three-level atom via intensity-dependent coupling have been studied. The discussion is centered on the influence of detuning and initial photon number on the field entropy evolution. The results show that the behavi or of the field entropy is non-periodic for the cases of small detuning and weak initial light field,being similar to the single-photon Jaynes-Cummings model (JCM). On the contrary,the field entropy evolution is periodic for the cases of large detuning or strong initial light field,being similar to the two-photon JCM

Dynamics of Information Entropies of Atom-Field Entangled States Generated via the Jaynes–Cummings Model

Razieh Pakniat, Mohammad Kazem Tavassoly, Mohammad Hossein Zandi

Abstract In this paper we have studied the dynamical evolution of Shannon information entropies in position and momentum spaces for two classes of (nonstationary) atom-field entangled states, which are obtained via the Jaynes–Cummings model and its generalization. We have focused on the interaction between two- and Ξ-type three-level atoms with the single-mode quantized field. The three-dimensional plots of entropy densities in position and momentum spaces are presented versus corresponding coordinates and time, numerically. It is observed that for particular values of the parameters of the systems, the entropy squeezing in position space occurs. Finally, we have shown that the well-known BBM (Beckner, Bialynicki-Birola and Mycielsky) inequality, which is a stronger statement of the Heisenberg uncertainty relation, is properly satisfied.

Properties of field quantum entropy evolution in the Jaynes–Cummings model with initial squeezed coherent states field

Liu Wang-Yun, Yuying An, Yang Zhi-yong

The properties of the field quantum entropy evolution in a system of a single-mode squeezed coherent state field interacting with a two-level atom is studied by utilizing the complete quantum theory, and we focus our attention on the discussion of the influences of field squeezing parameter γ, atomic distribution angle θ and coupling strength g between the field and the atom on the properties of the evolution of field quantum entropy. The results obtained from numerical calculation indicate that the amplitude of oscillation of field quantum entropy evolution decreases with the increasing of squeezing parameter γ, and that both atomic distribution angle θ and coupling strength g between the field and the atom can influence the periodicity of field quantum entropy evolution.
