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…
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…
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…
