Physics:Reversible reference system propagation algorithm

Short description: Time-stepping algorithm in molecular dynamics

Reversible reference system propagation algorithm (r-RESPA) is a time stepping algorithm used in molecular dynamics.

It evolves the system state over time,

$\mathrm{\Gamma }(t)=e^{iLt}\mathrm{\Gamma }(t=0)$

where the L is the Liouville operator.
