Floquet Control of Electron and Exciton Transport in Kekulé-Distorted Graphene
Sita Kandel, Godfrey Gumbs
This work investigates the Floquet dynamics of electrons and excitons (particle-hole pairs) in a Dirac material referred to as Kekulé-distorted graphene. Specifically, we examine t…
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…
Magnetoplasmons in magic-angle twisted bilayer graphene
Thi-Nga Do, Po-Hsin Shih, Godrey Gumbs
The magic-angle twisted bilayer graphene (MATBLG) has been demonstrated to exhibit exotic physical properties due to the special flat bands. However, exploiting the engineering of…
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…
Polarizability, plasmons, and screening in 1T-MoS with tilted Dirac bands
Antonios Balassis, Godfrey Gumbs, Oleksiy Roslyak
In the presence of an external vertical electric field and strain, it is evident that 1T-MoS exhibits tilted Dirac bands which are valley-spin-polarized. Additionall…
Plasmon damping rates in Coulomb-coupled two-dimensional layers in a heterostructure
Dipendra Dahal, Godfrey Gumbs, Andrii Iurov +1
The Coulomb excitations of charge density oscillation are calculated for a double-layer heterostructure. Specifically, we consider two-dimensional (2D) layers of silicene and graph…
