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…

Optical conductivity of a metal near an Ising-nematic quantum critical point
Songci Li, Prachi Sharma, Alex Levchenko +1
We study the optical conductivity of a pristine two-dimensional electron system near an Ising-nematic quantum critical point. We discuss the relation between the frequency scaling…
