Effect of conical intersections on chemical reactivity of ultracold molecules in optical potentials

Abstract

Major Goals: We investigated the chemical reactivity and quenching mechanisms between small molecules with conical intersections (CIs) at temperatures below a few milli Kelvin, where quantum effects and threshold phenomena dominate collisions. During this investigation we searched for dynamic signatures of non-adiabatic passage through conical intersections to distinguish relaxation and reaction pathways. In more detail the goals are: 1) Carry out electronic structure calculations of the short- and long-range potential surfaces for cold and ultracold molecules colliding with each other or with other atoms; 2) Locate and determine properties of conical intersections for the different molecular systems under investigation; 3) Build a bridge between computational approaches developed within the physical chemistry community and advanced tools for describing ultracold collisions of atoms and molecules used in the atomic physics community.
