Non-linear optical effects and third-harmonic generation in superconductors: Cooper-pairs vs Higgs mode contribution
T. Cea, C. Castellani, L. Benfatto
The recent observation of a transmitted Thz pulse oscillating at three times the frequency of the incident light paves the way to a new protocol to access resonant excitations in a…

Non-relativistic dynamics of the amplitude (Higgs) mode in superconductors
T. Cea, C. Castellani, G. Seibold +1
Despite the formal analogy with the Higgs particle, the amplitude fluctuations of the order parameter in weakly-coupled superconductors do not identify a real mode with a Lorentz-i…
