Normally ordered expansion of the inverse of the coordinate operator and the momentum operator

Hong-Yi Fan, Liang Fu

Published Apr 24, 2003• 15 citations

Abstract

We derive the normally ordered expansion formulae of 1/ n and 1/ n by virtue of the method of integral within an ordered product of operators in the sense of the principal value integral, where , are the coordinate and momentum operator, respectively. Application of the new formula is briefly discussed.

Normally ordering the Dirac's radial momentum operator and the power of radial coordinate operators by virtue of the IWOP technique

Hong-Yi Fan, Junhua Chen

By virtue of the technique of integration within an ordered product of operators we derive the normal ordering expansion of the Dirac's radial momentum operator. To realize this goal, we also derive some operator identities of the power of radial coordinate operators. They are useful in calculating expectation values in the coherent state.

Recast combination functions of coordinate and momentum operators into their ordered product forms*

Lei Wang, Xiang‐Guo Meng, Ji‐Suo Wang

By using the parameter differential method of operators, we recast the combination function of coordinate and momentum operators into its normal and anti-normal orderings, which is more ecumenical, simpler, and neater than the existing ways. These products are very useful in obtaining some new differential relations and useful mathematical integral formulas. Further, we derive the normally ordered form of the operator (fQ + gP)−n with n being an arbitrary positive integer by using the parameter tracing method of operators together with the intermediate coordinate–momentum representation. In addition, general mutual transformation rules of the normal and anti-normal orderings, which have good universality, are derived and hence the anti-normal ordering of (fQ + gP)−n is also obtained. Finally, the application of some new identities is given.

Meng Xiang-Guo, Ji‐Suo Wang, Liang Bao-Long

In this paper by virtue of the technique of integration within an ordered product (IWOP) of operators and the intermediate coordinate-momentum representation in quantum optics, we derive the normal ordering and antinormal ordering products of the operator ( fQ + gP ) n when n is an arbitrary integer. These products are very useful in calculating their matrix elements and expectation values and obtaining some useful mathematical formulae. Finally, the applications of some new identities are given.

Normally Ordered Expansion of the Even-Power of the Radial Coordinate Operator

Fan Hong‐Yi

By virtue of the technique of integration within an ordered product of operators we derive the concise normally ordered expansion of the even-power of the radial coordinate operator via the equation = ∫ d 3 x | x ⟩⟨ x | r , where | x ⟩ is the three-dimensional coordinate eigenvector, and r = ( x 2 + y 2 + z 2 ) 1/2 . The application to perturbation theory is briefly discussed.

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.
