Computing light induced molecular dynamics
Compared to classical molecular dynamics modeling software, NEXMD introduces the interaction between electron and nuclear motions (vibrations) that drives exciton migration and splitting. NEXMD simulations can be used to investigate a variety of light-induced processes (i.e. bond breaking reactions and isomerization, energy and charge transfer, exciton trapping) that are relevant for technological applications.
The NEXMD software introduces several new theoretical advances. For the first time, dielectric environment can be included in the exciton dynamics. The new solvent models reveal intricate details of how the environment can play a critical role in stabilizing charge transfer and influencing the lifetime and migration of excitons. The NEXMD also incorporates new algorithms allowing simulations to reach unprecedented length and timescales allowing simulation results to be directly connected to experiments.
