Statistical fractional-photon squeezed states

Physical Review A, 1989
We construct a large class of squeezed states realized in terms of density matrices. The moments of the canonical variable q^ and the number operator n^ distributions are analytically evaluated. The new states can be simultaneously squeezed in q^ and n^ to any desired amount and exhibit almost Gaussian shape in the former and strongly sub-Poisson ...

Photon Statistics in Adaptive Optics

Optics and Photonics News, 1999
ABSTRACT Random aberrations due to atmospheric turbulence determine the angular resolution of ground-based telescopes. Adaptive optics systems compensate the wavefront degradation before detection. Although systems with a large number of subapertures in the wavefront sensor and of actuators in the deformable mirror provide the best results, they are ...

Theory of the two-photon micromaser: Photon statistics

Physical Review A, 1990
Exact results for the photon statistics of a two-photon micromaser are presented, including the effect of finite detuning of the intermediate level. A periodic dependence on interaction times is shown to arise for large detunings, when sufficiently long interaction times are considered. Some typical photon-number distributions are shown, including some

Nonclassical photon statistics

Physical Review A, 2006
Some nonclassical properties of a particular state of light are demonstrated by computing the Wigner function. A quantum model of generating this state is proposed. A criterion called the distance variation difference is introduced to measure how far any state is from its corresponding coherent state.

Hyper-Poisson Photon Statistics

JETP Letters, 2020
The statistical distribution for the number of bosons in a specified subsystem of a finite-dimensional multilevel system is obtained and investigated under conditions for which the total number of particles is a random variable characterized by the Poisson distribution.
