GPU implementation of mixed quantum-classical Liouville molecular dynamics without momentum jump
A paper posted to arXiv describes a GPU implementation of mixed quantum-classical Liouville molecular dynamics that avoids the momentum jump approximation. The method targets nonadiabatic molecular dynamics simulations and is presented as a route to larger systems and longer timescales.

If the GPU code is released and validated, this could make mixed quantum-classical Liouville dynamics practical for simulating condensed-phase photochemical reactions over picosecond timescales within the next two years.
GPU acceleration lowers per-trajectory cost, and removing the momentum jump simplifies propagation, but adoption depends on benchmarking against established surface-hopping methods and availability to the chemistry community.
