Description

Abstract We describe PERTURB, a special purpose algebraic manipulation program which calculates vibrational eigenvalues in coupled oscillator systems. PERTURB implements the method of generalized algebraic quantization (AQ), in which Van Vleck perturbation theory is formulated in a mock phase space. The phase space formulation enables quantum and classical perturbation theory to be treated on the same footing, and allows the systematic calculation of corrections to classical perturbation results in po...
