Real-time Time dependent density functional theory gives us access to detailed evolution of quantum electronic system, both in the linear and the non-linear regime.
As the power and scale of TDDFT computer simulations grows, new phenomena can be captured and studied by this technique.
In this talk, we present a new method and simulation results regarding materials undergoing particle radiation and its relationship to the optical response and conductivity.
We obtain that there is a minimum of the DC-electrical conductivity as a function of current in a disordered metallic system and present a model that can explain these simulation results.
