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…

Charge density response in layered metals: retardation effects, generalized plasma waves and their spectroscopic signatures
Francesco Gabriele, Riccardo Senese, Claudio Castellani +1
Transverse plasma polaritons and longitudinal plasmons describe the propagation of light-matter modes in an isotropic metal. However, in a layered metal the anisotropy of the bare…
