Non-equilibrium dynamics of vibrationally coupled electrons excited by coherent radiation

ORAL

Abstract

The non-equilibrium dynamics of matter induced by coupling to light fields have made it possible to induce electronic phases of matter that may not exist at equilibrium, and which can be probed by optical and time-resolved spectroscopy. Transient superconductivity induced in atomic solids as a result of enhancement of atomic vibrations excited by light presents one exciting avenue. Here we employ tensor network methods to simulate the dynamics of a metal driven to a highly excited state at initial time by a pump that excites specific vibrational modes. We study the evolution with time of electronic and vibrational observables and observe non-trivial dynamics of density wave and superconducting correlations.
