Properties of Squeezed Binomial States and Squeezed Negative Binomial States
Journal of Modern Optics, 1991The effect of squeezing on binomial and negative binomial state has been studied in terms of quasiprobability of Wigner function and their photon number distributions. The results presented for squeezed binomial (negative binomial) states may be useful when one makes transients from squeezed coherent states to squeezed number (quasi- thermal) states.

Coordinate representation of squeezed states
Physical Review A, 1988We obtain the wave function in the coordinate representation of the one-mode squeezed states || ζ, α>=exp(ζa ^2 -ζa 2 )exp(αa^-αa)||0>. The wave function is a displaced Gaussian with center and width depending upon the parameters α and ζ.

Squeezed vacuum state in lossy channel as a squeezed thermal state
Modern Physics Letters B, 2015In this paper, we alternatively study the evolution of squeezed vacuum state (SVS) in lossy channel by virtue of the phase space method. By using the formula of Wigner function (WF) in coherent representation and [Formula: see text] representation of quantum density operator, the WF formula in lossy channel is derived.

‘‘Squeezed states’’ in Helmholtz optics
Physical Review A, 1993Squeezed states have been described in optics with the mathematics of quantum mechanics. Yet, electromagnetic fields of a single color obey the Helmholtz equation, of which the Schrodinger equation is but the paraxial (parabolic) approximation. We extend the ordinary squeezed states to solutions of the Helmholtz equation that contain them as their ...

Phase uncertainties of a squeezed state
Physical Review A, 1994We investigate various measures of phase uncertainty in their dependence on the average number of photons for the case of a phase squeezed state. We use the following three measures: (i) the geometrical uncertainty (\ensuremath{\delta}${\mathit{cphi}}_{\mathit{g}}$${)}^{2}$, (ii) the dispersion (\ensuremath{\delta}${\mathit{cphi}}_{\mathit{d}}$${)}^{2}$

On the Coherent States and the Squeezed States
Chinese Physics Letters, 1995In this paper the coherent and the squeezed state of the bose field is written as a universal form by means of a projector which transforms the old vacuum state to the new vacuum state. The transformed vacuum state is the coherent state or the squeed state. Our result is equivalent to the original definitions.

Generating superposition of squeezed states and photon-added squeezed states
Physica ScriptaAbstract The scheme of an arrangement is considered for the preparation of some non-classical superposed states from squeezed states by using the optical parametric amplifier (OPA) apparatus, which is based on an idea recently proposed to generate photon-added states from the coherent states of light.

Squeezing Properties of the Generalized Multimode Squeezed States
Communications in Theoretical Physics, 2001By means of the invariance of Weyl ordering under similar transformations we derive the explicit form of the generalized multimode squeezed states. Moreover, the completeness relation and the squeezing properties of the generalized multimode squeezed states are discussed.
