      "summary_nl": "We intend to implement and extensively benchmark accurate and computationally efficient inter-atomic forces in the framework of quantum Monte Carlo methods. These developments will allow us to perform calculations of the geometrical changes and dynamical relaxation following photo-excitation in complex bio-molecules. \n\nIn particular, we will take the first steps in the investigation of one of the most fundamental photo-induced processes in biology, namely, the primary event of vision in the vertebrate eye. Even though this process has been the subject of decades of theoretical and experimental studies, the debate on the exact nature of the molecular mechanism underlying this primary event is still open. With the requested CPU time, we will first perform an extensive investigation of the excited-state relaxation of retinal protonated Schiff base chromophores in the gas phase, ranging from small models to the full 11-cis chromophore.",
