Within the tutorial we will introduce the technology behind generating high field THz lights pulses and their application in driving collective dynamics in superconductors. In addition, we find a finite Higgs-like response above Tc that might be interpreted as finite pairing amplitude even above Tc.

We identify the driven Higgs amplitude response of the superconducting order parameter in three archetypal families of cuprate thin films and we report on a novel collective mode universally exhibited by optimally doped samples. Here we report on 'Higgs spectroscopy' in cuprate superconductors that we accomplished by using a high-field multicycle THz pulse, which nonlinearly couples to the superconducting condensate and leads to characteristic third harmonic generation.

In particular the collective dynamics of the superconducting order parameter, the Higgs mode, was not accessible so far. Stefan Kaiser, MD is a board certified preventive medicine physician in Virginia, Minnesota. Despite intensive spectroscopic measurements of these ordered states, yet the microscopic mechanism behind high-Tc superconductivity is still lacking.

The complex phase diagram of cuprate high-Tc superconductor is due to an intriguing interplay of different orders such as the pseudogap, or charge order.
