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…
Symmetries of -foams
You Qi, Louis-Hadrien Robert, Joshua Sussan +1
We give an action of a Lie subalgebra of the Witt algebra on foams. This action is compatible with the -foam evaluation formula. In particular, this endows states…
Non-semisimple Levin-Wen Models and Hermitian TQFTs from quantum (super)groups
Nathan Geer, Aaron D. Lauda, Bertrand Patureau-Mirand +1
We develop the categorical context for defining Hermitian non-semisimple TQFTs. We prove that relative Hermitian modular categories give rise to modified Hermitian WRT-TQFTs and pr…
Developing a semiclassical Wentzel-Kramers-Brillouin theory for model
Kathy Blaise, Chinedu Ejiogu, Andrii Iurov +3
We have developed a complete semiclassical Wentzel-Kramers-Brillouin (WKB) theory for model which describes a wide class of existing pseudospin-1 Dirac cone mater…
Plasmon damping rates in Coulomb-coupled two-dimensional layers in a heterostructure
Dipendra Dahal, Godfrey Gumbs, Andrii Iurov +1
The Coulomb excitations of charge density oscillation are calculated for a double-layer heterostructure. Specifically, we consider two-dimensional (2D) layers of silicene and graph…
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…
