Abstract
We describe a Fortran program which calculates the reduced density matrix of a one-dimensional quantum mechanical continuous or discrete system coupled to a harmonic dissipative environment. The algorithm is based on Feynman's path integral formulation of time-dependent quantum mechanics. An adiabatic reference is employed to obtain accurate propagators and the harmonic bath is replaced by an influence functional which is discretized by optimal discrete variable representations. A propagator ...
