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,…
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…
