Enhanced superconductivity in palladium hydrides by non-perturbative electron-phonon effects
Raffaello Bianco, Ion Errea
Palladium hydrides exhibit the largest isotope-effect anomaly in superconductivity: replacing hydrogen with heavier isotopes increases the superconducting critical temperature. Alt…
Non-perturbative theory of the electron-phonon coupling and its first-principles implementation
Raffaello Bianco, Ion Errea
The harmonic approximation of ionic fluctuations and the linear coupling between phonons and electrons provide the standard framework to compute, from first principles, the contrib…
Real-space understanding of electron-phonon coupling in superconducting hydrides
Trinidad Novoa, Raffaello Bianco, Julia Contreras-GarcÃa +1
Electron-phonon coupling is at the origin of conventional superconductivity, enabling the pairing of electrons into Cooper pairs. The electron-phonon matrix elements depend on the…
Electron-mediated anharmonicity and its role in the Raman spectrum of graphene
Nina Girotto Erhardt, Aloïs Castellano, J. P. Alvarinhas Batista +4
The Raman active G mode in graphene exhibits strong coupling to electrons, yet the comprehensive treatment of this interaction in the calculation of its temperature-dependent Raman…
Lattice thermal conductivity in the anharmonic overdamped regime
ÄorÄe DangiÄ, Giovanni Caldarelli, Raffaello Bianco +2
In crystalline materials, low lattice thermal conductivity is often associated with strong anharmonicity, which can cause significant deviations from the expected Lorentzian linesh…
