Abstract

A new set of non-naive generalizations of the squeezed coherent states recently discussed by Fisher, Nieto, and Sandberg is given, based on generalized Bose operators.

Impossibility of naively generalizing squeezed coherent states

Robert A. Fisher, Michael Martin Nieto, Vernon D. Sandberg

Pertinent properties of the unitary operators that create coherent states and squeezed coherent states are discussed. We show that certain generalizations of squeezed coherent states do not exist. This is accomplished by demonstrating that for the generalized squeeze operators ${U}_{k}=\mathrm{exp}(i{A}_{k})=\mathrm{exp}[{z}_{k}{({a}^{\ifmmode\dagger\else\textdagger\fi{}})}^{k}+i{h}_{k\ensuremath{-}1}\ensuremath{-}{({z}_{k})}^{*}{a}^{k}]$, $〈0|{U}_{k}|0〉$ diverges, $k>2$. This implies that $|0〉$ is not an analytic vector of ${A}_{k}$ for all $k>2$, where ${h}_{k\ensuremath{-}1}$ is a Hermitian polynomial in $a$ and ${a}^{\ifmmode\dagger\else\textdagger\fi{}}$ up to powers of ($k\ensuremath{-}1$).

The Statistical Properties of a New Type of Photon-Subtracted Squeezed Coherent State

Jun Zhou, Jun Song, Hao Yuan +1 more

We construct a new type of photon-subtracted squeezed coherent state (PSSCS) based on a squeezed coherent state (SCS) [ Phys. Lett. A 220 (1996) 81 ]. Some of the statistical properties of the PSSCS, such as Mandel's Q parameter and photon-number distribution, are investigated and the corresponding non-classicality is discussed.

Generalized Two-mode Squeezed States

Lu-Bi Deng, Lian-zhou Zhang, Song-gen Sun

A new generalized two-mode squeezed state which has less fluctuation in one quadrature phase then the usual two-mode squeezed state at the expense of increased fluctuation in the other quadrature is proposed. The coordinate representations and normally ordered expansions of the generalized two-mode squeeze operators and are given. The wavefunction of the generalized two-mode squeezed coherent state is obtained. The non-classical properties of the state such as squeezing and sub-Poissionian statistics are discussed.
