How to activate and detect the Higgs mode in superconductors — •Dirk Manske — Max Planck Institute for Solid State Research, Heisenbergstrasse 1, 70569 Stuttgart, Germany

Higgs Spectroscopy is a new and emergent field [1-3] that allows to classify and determine the superconducting order parameter by means of ultra-fast optical spectroscopy. There are two established ways to activate the Higgs mode in superconductors, namely a single-cycle *quench* or an adiabatic, multicycle *drive* pulse. In the talk I will review and report on the latest progress on Higgs spectroscopy, in particular on the role of the third-harmonic-generation (THG) [4-6,9] and the possible IR-activation of the Higgs mode by impurities or external dc current [7,8]. Finally, I discuss recent results on Non-Equilibrium Anti-Stokes Raman Scattering (NEARS) [10,11], where the Higgs mode, for the first time, has been observed directly.
