Suppressed plasmon excitations, enhanced damping and static screening in Kek-Y strained model
Jean Marseille, Teresa Lee, Andrii Iurov +3
We performed a rigorous theoretical and numerical investigation into the polarization function, plasmon excitations, and plasmon damping in the Kek- model, a two-dimensional mat…
Surface effects on the plasmons in two-dimemsional heterostructures: Application to tilted semi-Dirac materials
Teresa Lee, Godfrey Gumbs, Thi Nga Do +2
We derived closed-form analytic expressions for the plasmon dispersion equations for two and three monolayers embedded in a non-uniform dielectric medium with a surface. There is n…
Exploring stable long-lifetime plasmon excitations in the Lieb lattice
Andrii Iurov, Liubov Zhemchuzhna, Godfrey Gumbs +1
The subject of the present paper is a thorough numerical investigation of plasmon expectations, their dispersions and damping within a Lieb lattice. The Lieb lattice is known for i…
Polarizability and plasmons in pseudospin-1 gapped materials with a flat band
Liubov Zhemchuzhna, Andrii Iurov, Godfrey Gumbs +1
The collective electronic properties of various types of pseudospin- Dirac-cone materials with a flat band and finite bangaps in their energy spectra are the subject of our repo…
Self-consistent quantum-kinetic theory for interacting drifting electrons and force-driven phonons in a 1D system
Xuejun Lu, Danhong Huang
A self-consistent quantum-kinetic model is developed for studying strong-field nonlinear electron transport interacting with force-driven phonons within a quantum-wire system. For…
Plasmons in single- and double-component helical liquids: Application to two-dimensional topological insulators
O. Roslyak, Godfrey Gumbs, D. H. Huang
The plasmon excitations in proposed single- and double-component helical liquid (HL) models are investigated within the random-phase approximation, by calculating the density-densi…
