Title: Vibrational spectroscopy from first principles

Many of us at CCQ work on accurate solutions of the many-electron problem, describing the correlated dynamics of electrons interacting by Coulomb interactions.  I have recently been interested in an equally serious attack on the description of atomic vibrational dynamics from first principles.  This talk will be the product of my own quarantine-induced, non-exhaustive survey of the field.  My goal is to rigorously define the problem of interest and to highlight the challenges faced and some paths forward.  In particular, I think tensor network approaches represent some of the most promising methods for the simulation of vibrational dynamics.
