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…
Exploring non-trivial band structure and spin polarizations in -wave altermagnets tailored by anisotropic optical fields
Andrii Iurov, Liubov Zhemchuzhna, Tiyhearah Danner-Jackson
The subject of the present paper is a detailed theoretical investigation of the energy spectrum and bandgaps, as well as topological and collective properties and linear response,…
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…
Influence of Dynamical Floquet Spectrum on the Plasmon Excitations and Exchange Energy of tilted monolayer 1TMoS
Sita Kandel, Godfrey Gumbs, Antonios Balassis +2
It is now well established that a high-frequency electromagnetic dressing field within the off-resonance regime significantly modifies the electronic transport and optical properti…
