“…Due to the interest of the quadrature squeezing properties, we investigate these characteristics for our -CSs. To this end we follow two approaches based on the Heisenberg and the Schrödinger-Robertson uncertainty inequalities lead to strong and weak squeezing, respectively 28 , 55 , 68 , in which the squeezing conditions for the quadrature x ( p ) are reached since the following inequalities are established and the strongest and weakest squeezing effects are obtained when these quantities are equal to . Using the relations ( 17 ) and ( 18 ), one can obtain the strong and weak squeezing conditions for the quadrature x ( p ) on the -CSs.…”

The coherent states in the parity deformed analog of standard boson Glauber coherent states are generated, which admit a resolution of unity with a positive measure. The quantum-mechanical nature of the light field of these para-Bose states is studied, and it is found that para-Bose order plays an important role in the nonclassical behaviors including photon antibunching, sub-Poissonian statistics, signal-to-quantum noise ratio, quadrature squeezing effect, and multi-peaked number distribution. Furthermore, we consider the Jaynes-Cummings model of a two-level atom in a para-Bose cavity field with the initial states of the excited and Glauber coherent ones when the atom makes one-photon transitions, and obtain exact energy spectrum and eigenstates of the deformed model. Nonclassical properties of the time-evolved para-Bose atom-field states are exhibited through evaluating the fidelity, evolution of atomic inversion, level damping, and von Neumann entropy. It is shown that the evolution time and the para-Bose order control these properties.
