Abstract

A recursive graphical approach for the evaluation of two-body operator matrix elements is presented. This new approach is simpler as well as clearer compared to other approaches.

Two-body-operator matrix-element factorization technique in U(n)↓ SN unitary bases: Raising-raising operators

R. D. Kent, M. Schlesinger, Pardu S. Ponnapalli

A detailed exposition of explicit formulas used in the evaluation of raising-raising forms of two-body-operator matrix elements is presented. The methods are based on the use of the unitary-group distinct-row tabular-graphical representation of the many-particle basis. All matrix elements are expressible in the form of scalar and 2\ifmmode\times\else\texttimes\fi{}2 matrix factors. In order to facilitate the derivations of simple, computationally efficient forms for the matrix factors we develop a calculus based on elementary graphs. The methods are applicable to systems of particles involving spins greater than (1/2 and reduce to previously known results for the case of spin (1/2.

Iterative method for evaluating the matrix representation of the generators in the unitary-group approach

A. Lev, M. Schlesinger, R. D. Kent

An iterative method is presented for the evaluation of the matrix representation of the group generators in the unitary-group approach to many-electron systems. The method yields, in addition, closed-form expressions and selection rules for nonvanishing matrix elements. Generator products (two-body operators) are treated by a scalar-product method.

Two-body-operator matrix element factorization technique in U(n)↓ SN unitary bases. II. Raising-lowering operators

R. D. Kent, M. Schlesinger, Pardu S. Ponnapalli

A detailed exposition of explicit formulas used in the evaluation of raising-lowering forms of two-body-operator matrix elements is presented. The methods are based on the use of the unitary group distinct row table and graphical representation of the many-particle basis. All matrix elements are expressible in terms of scalar and simple matrix factors. In order to facilitate the derivations of simple, computationally efficient forms for the matrix factors, we utilize a recently developed calculus based on elementary graphs. The methods are applicable to systems of particles involving spins greater than (1/2 and reduce to previously known results for the case of spin (1/2.
