The Coherent-State Method of Normally Ordering Multimode Exponential Operators

Gong Ren-shan

Published Apr 1, 1992• 0 citations
Publisher

Abstract

This work shows that the coherent-state method provides us a very simple approach to normally ordering multimode exponential operators, many of which can't be normally ordered simply by the technique of integration within an ordered product (IWOP).

Normally ordering some multimode exponential operators by virtue of the IWOP technique

Fan Hong-Yi

The author shows that the technique of integration within an ordered product (IWOP) provides one with a very simple approach to deriving the normal product form of some multimode exponential operators, which greatly simplifies the calculations of normalising some state vectors in Hilbert space.

The IWOP Method of Normally Ordering Multimode Exponential Operators

Luo-Yu Feng

This paper states that the technique of integration within ordered product (IWOP) provides us with a generally effective approach to normally ordering multimode exponential operators. In fact, all the operators listed in Ref. [5] can be normally ordered by virtue of IWOP, in contrast to the comment of Ref. [5].

New approach for calculating the normally ordered form of squeeze operators

Fan Hong‐Yi, Haider R. Zaidi, John R. Klauder

A new method for directly obtaining the normally ordered form of single- and two-mode squeeze operators is presented. This method is based on the technique of ``integration within an ordered product.'' The operator expressions are derived using the coherent-state representation as well as the coordinate and the momentum representations. The method is very simple, and the approach has an intuitive basis that makes the squeezing property manifest at the outset.

Normally Ordered Form of Smoothed Wigner Operator and its Applications

Hong-Yi Fan, Guo-Liang Tong

Using the IWOP (integration within ordered product) technique, we derive a normally ordered form of the smoothed Wigner operator with which the smoothed Wigner function, that is specified only in the integral form in the literature, can be simplified. The application of the new form of the smoothed Wigner operator to the coherent state is also presented.

New Operator Identities and Combinatorics Studied by Virtue of IWOP Technique

Fan Hong-Yi, Ou-Yang Jing, Zhonghua Jiang

Using the coherent state representation we derive some new operator identities and study some mathematical relations in combinatorics. The technique of integral within an ordered product (IWOP) of operators plays an essential role in realizing our goal.
