Coherent driving of displacive Higgs fluctuations in superconductors
Jacopo Fiore, Irene Zanotti, Kota Katsumi +4
Intense phase-stable terahertz (THz) laser pulses can drive collective modes coherently via multi-photon excitation pathways in a manner different than the standard resonant mechan…
Fragile-to-strong glass transition in two-dimensional vortex liquids
Ilaria Maccari, Lara Benfatto, Claudio Castellani +2
The fragile-to-strong glass transition is a fascinating phenomenon that still presents many theoretical and experimental challenges. A major one is how to tune the fragility of a g…
Optical absorption in tilted geometries as an indirect measurement of longitudinal plasma waves in layered cuprates
Niccolò Sellati, Jacopo Fiore, Claudio Castellani +1
Electromagnetic waves propagating in a layered superconductor with arbitrary momentum with respect to the main crystallographic directions display an unavoidable mixing between lon…
Investigating Josephson plasmons in layered cuprates via nonlinear terahertz spectroscopy
Jacopo Fiore, Niccolò Sellati, Francesco Gabriele +4
Josephson plasmons in layered superconductors represent a natural source of optical non-linearity, thanks to their intrinsically anharmonic nature. Here we derive the selection rul…
Third harmonic generation from collective modes in disordered superconductors
G. Seibold, M. Udina, C. Castellani +1
Recent experiments with strong THz fields in both conventional and unconventional superconductors have clearly evidenced a marked third-harmonic generation below the superconductin…
Polarization dependence of the third-harmonic generation in multiband superconductors
T. Cea, P. Barone, C. Castellani +1
In a superconductor the third-harmonic generation (THG) of a strong THz pulse is enhanced below Tc by the resonant excitation of lattice-modulated charge fluctuations (LCF), which…
