The IWOP Method of Normally Ordering Multimode Exponential Operators

Luo-Yu Feng

Published Dec 1, 1993• 0 citations
Publisher

Abstract

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].

The Coherent-State Method of Normally Ordering Multimode Exponential Operators

Gong Ren-shan

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).

The Normal- and Antinormal-Ordered Decomposition Formulas of Multimode Exponential Operators

Song Tong-Qiang, Feng Jian, Gao Yun-Feng

We obtain the normally ordered form of the general multimode exponential operator by means of parameter differentiation method and its antinormally ordered form by virtue of the technique of integration within an ordered product of operators. As an application, we obtain a new completeness relation in -mode Fock space.

New Route to Deducing Integration Formulas by Virtue of the IWOP Technique

Hong-Yi Fan, Hongqi Li, Xing-Lei Xu

We point out a new route to deducing integration formulas, i.e., using the technique of integration within an ordered product (IWOP) of operators we derive some new integration formulas, which seems concise. As a by-product, some new operator identities also appear.
