Divide and Conquer ab initio semiclassical molecular dynamics for spectroscopic calculations of complex systems

Given the continuing revolution in "nano" and "bio" technologies, it is urgent for chemists to be able to carry out reliable quantum dynamics simulations of complex molecular systems. The goal of this ERC project named SEMICOMPLEX is to fill the gap between theory and experiment and provide the community with a user-friendly computational tool for nuclear spectra (IR, vibro-electronic, etc.) calculations of very complex systems. Present theoretical methodologies are hampered either by artificial nuclear potential interactions or by local potential perturbation assumptions. The semiclassical molecular dynamics method that I have been pioneering is not affected by these limitations because it is based on ab initio classical trajectories. The nuclear forces can be calculated by any electronic structure software and trajectories can explore the entire potential surface. The remaining challenge is to overcome the exponential scaling of computational power. We adopt a divide-and-conquer strategy to beat the curse of dimensionality. The new method will possibly allows chemists to have a more reliable spectral interpretation in a wider context up to the nanoscale. We are simulating several gas-phase molecules as well as pollutant photodegradation for environmental remediation. We are also looking into the vibro-electronic spectra of carcinogenic molecules adsorbed on TiO2 to better understand their route to photodegradation both by UV and visible light. We are reproducing the spectroscopic properties of molecular nano-texturing of titania films to understand their super-hydrophobic properties and their employment for outdoor cultural heritage preservation.
