A system to generate fortran programs for calculating configuration traces of angular momentum coupled product operators
Description
Title of program: CONTRACTION-COMPILER Catalogue Id: AAOP_v1_0 Nature of problem Three steps are usually involved in setting up a problem for numerical solution, 1) deriving algebraic expressions, 2) programming the equations, and 3) debugging the codes. Often step 1 requires repeated applications of fundamental rules, such as commutation and angular momentum recoupling in spectroscopy studies. While an individual may be able to recognize short cuts to speed up a derivation, by sheer speed and accuracy a computer programmed to manipulate the basic rules can prove to be the m ...
