∂R , and d nm (R)) and these are obtained from on-the-fly ab initio calculations. It bears reiterating that these equations of motion effectively describe nonadiabatic dynamics on multiple coupled electronic states despite the fact that time evolution is entirely classical in both the electronic and nuclear degrees of freedom. The ability to describe electronic coherences and the efficiency resulting from using classical dynamics render LSC a compelling option for large-scale ab initio NAMD simulations.
