Numerical methods for molecular photonics - the nonlinear nonperturbative response of molecules in intense laser fields

Different approaches are presented to simulate the nonlinear nonperturbative response of molecules to short intense laser fields. Different time scales, electronic vs. nuclear and transitions from bound (discrete spectra) to continuum states are inherent problems in current simulations. An overview of these problems encountered and estimates of computer requirements are made for this new branch of science and high technology: molecular photonics.
