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…
Quantized Hall current in topological nodal-line semimetal
Po-Hsin Shih, Thi-Nga Do, Godfrey Gumbs +3
Photocurrent acts as one of measurable responses of material to light, which has proved itself to be crucial for sensing and energy harvesting. Topological semimetals with gapless…
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…
Floquet engineering of titled and gapped Dirac materials
Andrii Iurov, Liubov Zhemchuzhna, Godfrey Gumbs +3
We have established a rigorous theoretical formalism for Floquet engineering, or investigating and eventually tailoring most crucial electronic properties of tetragonal molybdenum…
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…
Rashba spin-orbit coupling and quantum-interference effect for a pair of spin-correlated electrons in their tunneling and reflection under a step potential
Po-Hsin Shih, Godfrey Gumbs, Danhong Huang +2
We present both theory and numerical-computation results for the transmission and reflection probability currents of a charged particle across a potential step in the presence of a…
