Conclusions • We have introduced the MP/SOFT method for time-sliced simulations of quantum processes in systems with many degrees of freedom. The MP/SOFT method generalizes the grid-based SOFT approach to non-orthogonal and dynamically adaptive coherent-state representations generated according to the matching-pursuit algorithm. • The accuracy and efficiency of the resulting method were demonstrated in simulations of excited-state intramolecular proton transfer in HPO and HBT, as modeled by multidimensional ab initio reaction surface Hamiltonians, as well as in benchmark simulations of nonadiabatic quantum dynamics in pyrazine. • Further, we have extended the MP/SOFT method for computations of thermal equilibrium density matrices (equilibrium properties of quantum systems), finite temperature time-dependent expectation values and timecorrelation functions. The extension involves solving the Bloch equation via imaginary-time propagation of the density matrix in dynamically adaptive coherent-state representations, and the evaluation of the Heisenberg timeevolution operators through real-time propagation.
