In this work the role of magnetic Landau quantization in the dynamics and spectrum of diced lattice charge carriers is studied in terms of the associated pseudospin 1 Green’s function. The equations of motion for the 9 matrix elements of this Green

We study the transition pathways of a Lennard-Jones cluster of seven particles in three dimensions. Low lying saddle points of the LJ cluster, which can be reached directly from a minimum without passing through another minimum, are identified withou

Several aspects of the theory of plasmon resonant DC photoconduction are discussed here, in connection with recent observations involving a THz-irradiated grid-gated double-quantum-well FET.1 In this, we construct a classical model of nonlinear polar

A mean-field theory formalism is employed to analyze the nonlocal plasmon dispersion relation of monolayer graphene which is Coulomb coupled to a thick conductor. We calculate numerically the undamped plasmon excitation spectrum for arbitrary wave nu

We study theoretically the terahertz (THz) response of a bilayer of density-modulated two-dimensional electron gases, which we employ to model the actual double-quantum-well electron channel of a grid-gated field-effect transistor in which strong THz

We report here on the effect of a magnetic field on the coupling of 2D plasmons to nonlocal bulk plasmons. The present analysis extends our recent field-free study of the spectrum of coupled collective modes arising from electronic excitations within

We have examined the collective modes of a two-dimensional (2D) Landau-quantized magnetoplasma in a planar quantum well, including nonlocal 2D Bernstein modes, in interaction with surface and bulk optical phonons. The system considered is a 2D sheet

We report a systematic, fully three-dimensional theoretical examination of convective space-charge wave modes of a planar superlattice subject to negative differential miniband conductance (NDC) in a dc bias electric field. Our analysis is based on a

We refine the determination of the equilibrium density distribution in a grid-gated double-quantum-well FET, taking account of screening in the system using the Poisson equation. This calculation provides requisite input information needed for the an
