Dynamical polarization function, plasmons, their damping and collective effects in semi-Dirac bands

Gabrielle Ross-Harvey, Andrii Iurov, Liubov Zhemchuzhna +2

We have calculated the dynamical polarization, plasmons and damping rates in semi-Dirac bands (SDB's) with zero band gap and half-linear, half-parabolic low-energy spectrum. The ob…
