FIG. 16.
Results of an MCTDH/LCT simulation of retinal using Hahn-Stock model with an aim to maximize trans isomerized product. Top panel: time-dependent expectation values state-projection operators. The dark-magenta line corresponds to the ground electronic state in the cis configuration, the olive-green line corresponds to the first excited state in the cis configuration and the blue line corresponds to the first excited state in the trans configuration. Middle panel: the optimal pulse, in time domain, obtained for a propagation up to 2000 fs which maximizes the transfer of population to the trans ground state. Bottom panel: the Fourier transform of the time-domain pulse. Inset shows an enlarged view of an important part of the spectrum.
