Description

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We present in this paper the SOSpin library, which calculates an analytic decomposition of the Yukawa interactions invariant under SO (2N) in terms of an SU (N) basis. We make use of the oscillator expansion formalism, where the SO (2N) spinor representations are expressed in terms of creation and annihilation operators of a Grassmann algebra acting on a vacuum state. These noncommutative operators and their products are simulated in SOSpin through the implementation of doubly-l...
