Squeezing Properties of the Generalized Multimode Squeezed States

Communications in Theoretical Physics, 2001
By 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.

Properties of Squeezed Binomial States and Squeezed Negative Binomial States

Journal of Modern Optics, 1991
The 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.

NONLINEAR SQUEEZED VACUUM STATES: NONCLASSICAL PROPERTIES

International Journal of Modern Physics B, 2005
Some of the properties of nonlinear squeezed vacuum states associated with trapped ions are considered, especially the photon number distribution, the phase properties, the Husimi–Kano Q function and the Wigner–Moyal W function of these nonlinear squeezed vacuum states. The structure of these functions is shown to depend on the nonlinearity parameter,

Squeezing properties of a pulsating oscillator

Quantum and Semiclassical Optics: Journal of the European Optical Society Part B, 1995
The authors have investigated the time evolution of a quantum oscillator with a pulsating mass using the Lie-algebraic technique. Squeezing properties of the oscillator are numerically examined. The analyses indicate that the oscillator initially in a coherent state can have a very strong squeezing effect.

Higher-order squeezing properties and correlation functions for squeezed number states

Physical Review A, 1991
Higher-order squeezing conditions for squeezed number states are derived using a normal-ordering technique for calculating the moments of the field. Intrinsic higher-order squeezing is also investigated. It is found that the normally ordered moments of the quadrature operators are oscillating functions of the squeeze parameter.

SQUEEZING PROPERTIES OF COUPLED NONLINEAR OSCILLATORS

International Journal of Modern Physics B, 1990
In this paper the squeezing properties of the two-mode radiation field interacting with a nonliner nonabsorbing Kerr-like medium modelled as a two-mode anharmonic oscillator are studied. Time evolution of the variances of the radiation field initially prepared in the two-mode coherent state as well as the two-mode squeezed vacuum state are analyzed ...

Phase properties of superposed squeezed states

Optical Review, 2001
The phase properties of the superposed squeezed states are studied. The superposed squeezed states are obtained by inserting two squeezers in a Mach-Zehnder interferometer one for each arm. The visibility of the states as a measure of the coherence of the generated photons in the nonlinear interferometer is analyzed.

Basic properties of squeezed light

Soviet Physics Uspekhi, 1991
The physical picture of the properties of light in squeezed and in other nonclassical states is presented and compared with the properties of light in the classical coherent state. The theoretical basis of the description and the generation of squeezed light is presented, and a practical scheme for obtaining light in other of its nonclassical states is

Properties of superposition of squeezed states

Physics Letters A, 1997
Abstract We investigate some statistical properties of superposed squeezed states. The quasiprobability distribution functions, especially W ( α ) and Q ( α ), are calculated and discussed for these states. A generation scheme is proposed for both the squeezed generalized Schrodinger cat, or the squeezed number state.

Squeezing Properties of the Ion Traps

Communications in Theoretical Physics, 1997
With time and space transformation, we first solve the Schrodinger equation of the time-dependent harmonic oscillator (TDHO) system. The properties of the squeezing in the case of , i.e., the Paul trap and , namely a stable frequency interfered by a single-pulsing-type disturbance, are investigated by using function series expansion.
