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…

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…

Effect of magnetic field and chemical potential on the RKKY interaction in the - lattice

Oleksiy Roslyak, Godfrey Gumbs, Antonios Balassis +1

The interaction energy for the indirect-exchange or Ruderman-Kittel-Kasuva-Yosida (RKKY) interaction between magnetic spins localized on lattice sites of the - model…

Magnetoplasmons for the -T model with filled Landau levels

Antonios Balassis, Dipendra Dahal, Godfrey Gumbs +3

Using the -T model, we carried out analytical and numerical calculations for the static and dynamic polarization functions in the presence of a perpendicular magnetic field.…

Combined effect of doping and temperature on the anisotropy of low-energy plasmons in monolayer graphene

Godfrey Gumbs, Antonios Balassis, V. M. Silkin

We compare the two-dimensional (2D) plasmon dispersion relations for monolayer graphene when the sample is doped with carriers in the conduction band and the temperature is zer…

Effect of Temperature and Doping on Plasmon Excitations for an Encapsulated Double-Layer Graphene Heterostructure

Godfrey Gumbs, Dipendra Dahal, Antonios Balassis

We perform a comprehensive analysis of the spectrum of graphene plasmons which arise when a pair of sheets are confined between conducting materials. The associated enhanced local…
