NEGATIVE BINOMIAL STATES OF THE RADIATION FIELD AND THEIR EXCITATIONS ARE NONLINEAR COHERENT STATES

XIAO-GUANG WANG, HONG-CHEN FU

Published Aug 10, 1999• 21 citations

Abstract

We show that the well-known negative binomial states of the radiation field and their excitations are nonlinear coherent states. Excited nonlinear coherent states are still nonlinear coherent states with different nonlinear functions. We finally give an exponential form of the nonlinear coherent states and remark that the binomial states are not nonlinear coherent states.

EVEN- AND ODD-BINOMIAL STATES AS EIGENSTATES OF A NONLINEAR COMBINATION OF RADIATION FIELD OPERATORS

Hong-Yi Fan, Sicong Jing

We show that the even- and odd-binomial states are eigenstates of the definite nonlinear combination of radiation field operators, which generalizes the nonlinear coherent state theory in quantum optics.

TWO TYPES OF CORRELATED BINOMIAL-NEGATIVE BINOMIAL STATES AND THEIR NONCLASSICAL PROPERTIES

Hong-Yi Fan, Nai-Le Liu, HENG LI

Based on the single-mode binomial states and the negative binomial states, we construct two types of two-mode correlated states of the quantized radiation field. Their nonclassical properties are investigated. It is also shown that these states can be viewed as correlated su(2) and su(1,1) coherent states.

Excited Binomial States and Excited Excited Binomial States and Excited Negative Binomial States of the Radiation Field and Some of their Statistical Properties

Xiaoguang Wang, Hong‐Chen Fu

We introduce excited binomial states and excited negative binomial states of the radiation field by repeated application of the photon creation operator on binomial states and negative binomial states. They reduce to Fock states and excited coherent states in certain limits and can be viewed as intermediate states between Fock states and coherent states. We find that both the excited binomial states and excited negative binomial states can be exactly normalized in terms of hypergeometric functions. Base on this interesting character, some of the statistical properties are discussed.

GENERALIZED EXCITED NEGATIVE BINOMIAL STATES OF ELECTROMAGNETIC FIELD AND SOME OF THEIR NON-CLASSICAL PROPERTIES

H. H. Salah, Mahmoud Darwish, A.‐S. F. Obada

New states of electromagnetic field, generalized excited negative binomial states are introduced here. These states interpolate between the superposition of two excited coherent states and number states. The non-classical properties for these states are discussed, such as, second order correlation function, squeezing phenomena [normal squeezing and amplitude squared squeezing], phase properties in Pegg–Barnett formalism and the quasi-probability distribution functions (Q-function and Wigner function).

Statistical Properties and Algebraic Characteristics of Quantum Superpositions of Negative Binomial States

WANGXiao-Guang, FUHong-Chen

We introduce new kinds of states of quantized radiation fields, which are the superpositions of negative binomial states. They exhibit remarkable nonclassical properties and reduce to Schrodinger cat states in a certain limit.The algebras involved in the even and odd negative binomial states turn out to be generally deformed oscillator algebras.It is found that the even and odd negative binomial states satisfy the same eigenvalue equation with the same eigenvalue and they can be viewed as two-photon nonlinear coherent states. Two methods of generating such the states are proposed.``
