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…

Superpotentials, flat bands and the role of Quantum Geometry for the superfluid stiffness
T. Bauch, F. Lombardi, G. Seibold
Enhancing superconductivity through material design is a central goal in quantum materials research. Moire engineering, where twisting stacked layers creates long-wavelength modula…

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…
