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 ma…

Surface Response, Plasma Modes of coated Multi-Layered anisotropic Semi-Dirac Heterostructures
Teresa Lee, Godfrey Gumbs, Thi Nga Do +2
We derived closed-form analytical expressions for the surface response functions (SRFs) for heterostructure. We investigate structures consisting of up to three layered, coated het…

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…
