Recent developments of experimental techniques based on ultrafast spectroscopy have enabled the access to low energy collective modes in quantum materials in a time-resolved manner. In particular, the amplitude mode of the order parameter in superconductors, called the Higgs amplitude mode, has attracted a growing interest from the viewpoint of non-equilibrium dynamics in symmetry-broken ordered phases. In this presentation, I will introduce the study of the Higgs mode and other collective modes in conventional and unconventional superconductors using various nonlinear terahertz spectroscopic schemes.
