Optical conductivity and damping of plasmons due to electron-electron interaction
Prachi Sharma, Alessandro Principi, Giovanni Vignale +1
We re-visit the issue of plasmon damping due to electron-electron interaction. The plasmon linewidth can related to the imaginary part of the charge susceptibility or, equivalently…
Theoretical determination of the effect of a screening gate on plasmon-induced superconductivity in twisted bilayer graphene
Liangtao Peng, Indra Yudhistira, Giovanni Vignale +1
The microscopic pairing mechanism for superconductivity in magic-angle twisted bilayer graphene remains an open question. Recent experimental studies seem to rule out a purely elec…
Spin relaxation near a ferromagnetic transition
Matthew D. Mower, G. Vignale
We study spin relaxation in dilute magnetic semiconductors near a ferromagnetic transition, where spin fluctuations become strong. An enhancement in the scattering rate of itineran…
Luttinger-field approach to thermoelectric transport in nanoscale conductors
F. G. Eich, A. Principi, M. Di Ventra +1
Thermoelectric transport in nanoscale conductors is analyzed in terms of the response of the system to a thermo-mechanical field, first introduced by Luttinger, which couples to th…
Violation of the Wiedemann-Franz law in clean graphene layers
A. Principi, G. Vignale
The Wiedemann-Franz law, connecting the electronic thermal conductivity to the electrical conductivity of a disordered metal, is generally found to be well satisfied even when elec…
Current reversals in rapidly rotating ultra-cold Fermi gases
K. Bencheikh, S. Medjedel, G. Vignale
We study the equilibrium current density profiles of harmonically trapped ultra-cold Fermi gases in quantum Hall-like states that appear when the quasi-two-dimensional trap is set…
