In the previous paper, we adopted the method using quantum mutual entropy to measure the degree of entanglement in the time development of the Jaynes-Cummings model [1]. In this paper, we formulate the entanglement in the time development of the Jaynes-Cummings model with squeezed states, and then show that the entanglement can be controlled by means of squeezing.

We analyze here a nonclassical state produced by an atom-cavity field interaction. The two-level atom is passed through the single-mode electromagnetic cavity field. By deforming operators and introducing nonlinearity to classic Jaynes-Cummings model, we explore system in respect of nonlinear Hamiltonian. Assuming that excited coherent initially, analytic expression for vector entire obtained. ...

Abstract We discuss the elementary errors in Zhang’s (2021 New J. Phys. 23 093014) claimed exact solution of quantum Rabi model. The erroneous is seen to be nothing more than combined simpler Jaynes–Cummings and anti-Jaynes–Cummings models obtained by neglecting terms model Hamiltonian.

Analog quantum simulation---the technique of using one experimentally well-controlled physical system to mimic the behavior another---has quickly emerged as most promising near-term strategies for studying strongly correlated many-body systems. In particular, systems interacting photons, realizable in solid-state cavity and circuit QED frameworks, example, hold tremendous promise study nonequil...

There have been three attempts to date to establish foundations for the discipline of probability, namely the efforts of Kolmogorov (who rigorized the frequentist approach), de Finetti (who gave Bayesian notions of belief and betting odds a formal treatment) and RT Cox/ET Jaynes (who developed a Bayesian theory of probability based on reasonable expectation (Cox) and the optimal processing of i...

p(x) lnp(x)dx (1) Maximizing H subject to various side conditions is well–known in the literature as a method for deriving the forms of minimal information prior distributions; e.g. Jaynes (1968) and Zellner (1977). Jaynes (1982) has extensively analyzed examples in the discrete case, while in Lisman and Van Znylen (1972), Rao (1973) and Gokhale (1975), Kagan, Linjik continuous cases are consid...

In this paper we consider deterministic nonlinear time evolutions satisfying so called convex quasi-linearity condition. Such preserve the equivalence of ensembles and therefore are free from problems with signaling. We show that if family linear non-trace-preserving maps satisfies semigroup property then generated quasi-linear operations also possesses property. Next generalize Gorini-Kossakow...
