INTERMEDIATE STATES: SOME NONCLASSICAL PROPERTIES

In this article we consider in some detail some new classes of states. These states are intermediate states either between the pure number (Fock) states, and the (non-pure) chaotic state (thermal state), such as geometric state, or between the coherent state and number state such as binomial state. We extend our discussion to include some other states such as even (odd) coherent states, even (odd) binomial states, phased generalized binomial state … etc. In our study of these states we pay attention to a discussion of the nonclassical properties, besides the statistical properties, for example correlation functions, squeezing, and quasiprobability distribution functions (P-representation, W-Wigner, and Q-function). Furthermore we consider the field distribution and the photon number distribution, as well as the phase properties. Finally, some schemes for the production of these states are presented.
