Path-integral description of combined Hamiltonian and non-Hamiltonian dynamics in quantum dissipative systems

We present a numerical path-integral iteration scheme for the low-dimensional reduced density matrix of a time-dependent quantum dissipative system. Our approach simultaneously accounts for the combined action of a microscopically modeled pure-dephasing-type coupling to a continuum of harmonic oscil...
