Title: Nonlinear response of disordered superconductors: Higgs amplitude mode under the light
Maxim Dzero
Department of Physics, Kent State University
Abstract: In the past decade there have been an impressive progress made in studying conventional and unconventional superconductors using a pump-probe setup of the terahertz field experiments. In my talk I will first provide an overview of the state-of-the-art experimental techniques. I will proceed with the overview of the theoretical results on the problem of far-from-equilibrium superconductivity which pre-dated the recent experiments. Then I plan to discuss how experimental discoveries motivated the theorists to revisit now classical problems which remained unresolved for many years. In particular, I will discuss how the effects associated with impurity scattering may help in elucidating the dynamics of the amplitude Higgs mode in conventional superconductors.
