New prospective on information entropy using different initial states of the atom–field interaction

Abstract

We propose a new approach for introducing the long-life information entropy of the interaction between atom and electromagnetic field. Our approach is based on a comparison of the initial state of the field. The field is initialized in Pólya state, negative hypergeometric state, generalized nonclassical state, phase-like state and generalized hypergeometric state. Dynamics of entropy squeezing are examined. It is shown that a long-time approximately steady nonclassical behavior of the system can be obtained using specific values of the parameters associated with the initial state of system. An application of the developed method to obtain the long-lived information from different models is given.
