Properties of squeezed number states and squeezed thermal states

Physical Review A, 1989
Much attention has been given in the past to two classes of squeezed states: the squeezed vacuum and coherent states. Here we study the effects of squeezing on number states and on thermal field states. The statistical properties of these various squeezed states are discussed using the second-order correlation functions.

Multimode squeeze operators and squeezed states

Physical Review A, 1990
Multimode squeeze and rotation operators are defined such that they have extremely similar algebraic properties as those of their single-mode counterparts. It is shown that the introduction of {ital N}-mode squeeze operators provides a convenient set of parameters to describe the variances of the quadrature amplitudes in multimode Gaussian squeezed ...

Multiphoton squeezed states

Journal of the Optical Society of America B, 1987
The multiphoton squeezed states defined in this paper are generalizations of the conventional coherent (Glauber) and squeezed (Yuen) states previously discussed by many authors. We define multiphoton generalizations of the latter by a unified class of states that includes the Holstein–Primakoff realizations of SU(2) and SU(1, 1) as well as the standard

Vector squeezed states

Physical Review A, 1991
We study a two-mode squeezed state of the electromagnetic field, in which each mode is degenerate in frequency, but they have orthogonal polarizations. We use a degenerate four-wave-mixing geometry and two-photon transitions for these squeezed states. The modes are treated in a mean-field approximation that includes the effects of vacuum fluctuations ...

Squeezing and superposition states

Physical Review A, 1987
We present a new class of radiation field states which exhibit squeezed fluctuations. This new class of states are formed by a simple implementation of the superposition principle and are fundamentally different from the conventional two-photon coherent squeezed states.

Squeezed vacuum from amplitude squeezed states

Optics Letters, 1991
Squeezed vacuum permits adjustment of its relative phase to a chosen signal. If the signal is used as the probe in an interferometric measurement, the signal-to-noise ratio can be improved. We propose a system that generates squeezed vacuum, which consists of a laser diode that produces amplitude squeezed states and is phaselocked to a coherent signal,

Squeezed fermion states

Physical Review Letters, 1990
Summary: Fermionic squeezing is derived in analogy to squeezed light, but with two distinct features: (i) Intramode squeezing can be achieved by noise attenuation in the particle sector at the cost of noise amplification in the antiparticle sector (or vice versa).

Generalized multimode squeezed states

Physical Review A, 1993
The notion of squeezing is generalized to the case of multimodes. The multimode generalized squeezing operator has similar algebraic properties to those of the single-mode case and reduces to the usual two-mode squeezing operator in the case of two modes.
