Abstract

The completeness relation for the superposition pair coherent state is discussed.Based the phase operator and phase state introduced by Pegg and Barnett we study the phase probability distributions of the superposition pair coherent state and the numerical calculation.It is shown that the probability distributions of the superposition pair coherent state are regulated by the parameters of phase and superposition.

Based on our previous work, the phase state and phase operator introduced by Pegg and Barnett are generalized to two-mode q-deformed circumstances. With the aid of numerical method, the phase probability distributions of q-deformed pair coherent state are investigated. It is shown that these probability distributions of the state are regulated by the parameters of phase, the q-number and the magnitude of |ξ|. Therefore, the q-deformed pair coherent state exhibits different quantum interference properties.

Phase distribution of nonlinear coherent states

Barnana Roy, P Roy

Using the Pegg-Barnett formalism we study phase properties of nonlinear coherent states. We compute the Pegg-Barnett phase probability distribution of nonlinear coherent states and compare it with phase distributions associated with the Q function and the Wigner function. Squeezing properties of nonlinear coherent states with respect to the number and the phase operator are also studied.

Based on the definition of Pegg-Barnett phase state, the phase probability distribution funtions of coherent state are analytically calculated. It is shown that the phase probability distributicn curve is a straight line in vacuum state and that in coherent state is: the average distribution, → the Poisson distribution → the average distribution.

Phase properties of excited coherent states

Ravinder Nath, Satish Kumar Muthu

The phase properties of states generated by excitations on a coherent state have been studied by evaluating the expression for the phase probability distribution, using the recent formalism of Pegg and Barnett in which the existence of a Hermitian optical phase operator has been shown. This distribution has been further used to evaluate the variance of the phase operator and the number - phase uncertainty product.

The squeezing properties in the superposition state of the vacuum state and the coherent state are studied by using the measured phase operators introduced by Barnett S M and Pegg D T.The effects of superposition parameter p and coherent parameters(R,θ) on the squeezing properties are discussed.

From the definition of the phase state by Pegg and Barnett, an expression of phase coherent state for bosons is deduced, us statistical property is investigated and distribution probability and quantum fluctuation of the phase are calculated It is showed that appearance probability and quantum fluctuation of the phase in phase coherent state are biggish when the phase angle is bigger.
