Professor Artur Izmaylov, University of Toronto. "Topological phase effects in molecular dynamics beyond the Born-Oppenheimer approximation." Greater Boston Theoretical Chemistry Lecture.Abstract: The Born-Oppenheimer approximation for molecules introduces natural separation between dynamics of electrons and nuclei. This separation allows one to consider nuclear chemical dynamics independently from that of the electronic subsystem. However, there are also a few complications associated with cases when several electronic potential energy surfaces become similar in energy or even cross. The latter case often presents itself in the form of a conical intersection. For example, in many photochemical, charge and electronic energy transfer processes nuclear molecular dynamics proceeds near conical intersections. In this talk, I will discuss how non-trivial topological phases associated with conical intersections of electronic surfaces affect chemical dynamics of molecular systems and what intuitive picture can be extracted from exact numerical simulations for simple models.
