Quantum statistical properties of some new classes of intelligent states associated with special quantum systems

Abstract

Based on the nonlinear coherent states method, a general and simple algebraic formalism for the construction of ‘f-deformed intelligent states’ has been introduced. The structure has the potentiality to apply to systems with a known discrete spectrum as well as the generalized coherent states with known nonlinearity function f(n). As some physical appearance of the proposed formalism, a few new classes of intelligent states associated with ‘center-of-mass motion of a trapped ion’, ‘harmonious states’ and ‘hydrogen-like spectrum’ have been realized. Finally, the nonclassicality of the obtained states has been investigated. To achieve this purpose the quantum statistical properties using the Mandel parameter and the squeezing of the quadratures of the radiation field corresponding to the introduced states have been established numerically.
