Dynamical optical conductivity for gapped materials with a curved "flat" band
Andrii Iurov, Liubov Zhemchuzhna, Godfrey Gumbs +1
We have calculated the dynamical optical conductivity for materials in the presence of a finite bandgap in their energy bandstructure. This is a special type of e…

Finite-temperature plasmons, damping and collective behavior for model
Andrii Iurov, Liubov Zhemchuzhna, Godfrey Gumbs +3
We have conducted a thorough theoretical and numerical investigation of the electronic susceptibility, polarizability, plasmons, their damping rates, as well as the static screenin…
