Abstract:
We present a semiclassical (SC) approach for quantum dissipative dynamics, constructed on basis of the hierarchical{equation{of{motion (HEOM) formalism. The dynamical components considered in the developed SC{HEOM are wavepackets'' phase{space moments of not only the primary reduced system density operator but also the auxiliary density operators (ADOs) of HEOM. It is a highly numerically ecient method meanwhile takes into account the high{order e ects of system{bath couplings. The SC{HEOM methodology is exempli ed in this paper on the hierarchical quantum master equation (J. Chem. Phys. 131, 214111 (2009)) and numerically demonstrated on linear spectra of anharmonic oscillators.
