Query: Efficient and accurate surface hopping for long time nonadiabatic
  quantum dynamics   The quantum-classical Liouville equation offers a rigorous approach to
nonadiabatic quantum dynamics based on surface hopping type trajectories.
However, in practice the applicability of this approach has been limited to
short times owing to unfavorable numerical scaling. In this paper we show that
this problem can be alleviated by combining it with a formally exact
generalized quantum master equation treatment. This allows dramatic
improvements in the efficiency of the approach in nonadiabatic regimes, making
it computationally tractable to treat the quantum dynamics of complex systems
for long times. We demonstrate our approach by applying it to a model of
condensed phase charge transfer where our method is shown to be numerically
exact in regimes where fewest-switches surface hopping and mean field
approaches fail to obtain the either the correct rates or long-time
populations.
