Squeeze Cast Automotive Applications and Squeeze Cast Aluminum Alloy Properties

SAE Technical Paper Series, 1999
<div class="htmlview paragraph">The emergence of squeeze casting process for aluminum alloys has given material and design engineers a new alternative to conventional casting techniques: gravity permanent mold (GPM) and conventional (high velocity, high pressure) die casting.

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.

Phase properties of squeezed states of light

Optics Communications, 1989
Abstract Recently introduced unitary and hermitian phase operators are used to examine the phase properties of squeezed states of light with particular reference to the squeezed vacuum. The results differ markedly from previous calculations involving the Susskind and Glogower operators. The new formalism allows the construction of a phase probability

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 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 ...

Properties of the Squeezed Polarons in One Dimension

International Journal of Modern Physics B, 1998
An electron related squeezed phonon transformation is employed to investigate the ground state properties of the strongly coupled electron–phonon system in one dimension. It has been shown that the binding energy of the polaron and the interaction between the polarons are renormalized together with the energy reducement of the electron subsystem ...

On classical properties of thermal squeezed states

Journal of Physics A: Mathematical and General, 1991
The authors use the formalism of thermo field dynamics and the classical Cramer's theorem to show that if two quantum systems are prepared independently and their centre of mass is found to be a thermal squeezed state, then both systems were prepared in thermal squeezed states. This constitutes an alternative derivation of the quantum version of Cramer'

Phase Properties of Squeezed Number States

Journal of Modern Optics, 1991
We have studied the phase properties of the squeezed number states by evaluating the expression for the phase probability distribution and the phase variance. In addition, the expression for the photon-number distribution of the squeezed phase states has been evaluated.

Nonclassical statistical properties of fields in squeezed even and squeezed odd coherent states

Journal of the Optical Society of America B, 1993
We examine the nonclassical statistical properties of the squeezed even and the squeezed odd coherent states defined by the superposed states involving two squeezed coherent states with phase difference π between their displacement parameters. We demonstrate that the fields in the squeezed even coherent state can exhibit a remarkably enhanced squeezing

Properties of two-mode nonlinear squeezed vacuum and coherent squeezed vacuum states

Journal of Physics A: Mathematical and General, 2002
Summary: The construction of two \(f\)-analogues of the two-mode squeezed vacuum and coherent squeezed vacuum states are derived using deformation quantization methods. The statistical properties of these states are studied and the method of integration within an ordered product is used to derive several new completeness relations.
