Representation of the Coulomb Matrix Elements by Means of Appell Hypergeometric Function F2
Exact analytical representation for the Coulomb matrix elements by means of Appell’s double series F2 is derived. The finite sum obtained for the Appell function F2 allows us to evaluate explicitly the matrix elements of the two-body Coulomb interaction in the lowest Landau level. An application requiring the matrix elements of Coulomb potential in quantum Hall effect regime is presented.
