Lattice and surface effects in the out-of-equilibrium dynamics of the Hubbard model
We study, by means of the time-dependent Gutzwiller approximation, the out-of-equilibrium dynamics of a half-filled Hubbard-Holstein model of correlated electrons interacting with local phonons. Inspired by pump-probe experiments, where intense light pulses selectively induce optical excitations that trigger a transient out-of-equilibrium dynamics, here we inject energy in the Hubbard bands …
