Ab-initio Van der Waals electrodynamics: polaritons and electron scattering from plasmons and phonons in BN-capped graphene
Francesco Macheda, Francesco Mauri, Thibault Sohier
Plasmons and polar phonons are elementary electrodynamic excitations of matter. In 2d and at long wavelengths, they couple to light and act as the system polaritons. They also dict…

Born effective charges and vibrational spectra in super and bad conducting metals
Guglielmo Marchese, Francesco Macheda, Luca Binci +3
Interactions mediated by electron-phonon coupling are responsible for important cooperative phenomena in metals such as superconductivity and charge-density waves. The same interac…
