Quantum dynamical treatment of systems with many degrees of freedom

Multiconfiguration basis-set methods provide a way to accurately describe quantum dynamical processes in systems with many degrees of freedom or in a condensed phase environment. In this talk, the multilayer multiconfiguration time-dependent Hartree (ML-MCTDH) method [1] is discussed. The ML-MCTDH method is a variational basis-set approach that extends the original MCTDH method [2] to significantly larger systems. The performance of the method is illustrated by several applications, including the spin-boson model and extensions of this model with anharmonic potentials [3], photoinduced electron transfer processes at dye-semiconductor interfaces [4,5], as well as a model for electron transport through single molecule junctions.
