We present an extensive study of resonant two-dimensional (2D) plasmon excitations in
grating-gated quantum well heterostructures, which enable an electrical control of periodic …

We present a simulation tool, TETHYS (ie, Two-dimensional Emitter of THz, Hydrodynamic
Simulation), developed with the aim of studying hydrodynamic models for electronic …

We investigate an interplay between quantum geometrical effects and surface plasmons
through surface plasmonic structures, based on an electron hydrodynamic theory. First we …

We study the dispersion properties of electron plasma waves, or plasmons, which can be
excited in quantum plasmas in the nonlinear regime. In order to describe nonlinear electron …

The method of controlling the spectral and polarization characteristics of a terahertz (THz)
pulse during its amplification in nonequilibrium magnetized plasma is investigated. The …

A hydrodynamic model, which discards potential notation but couples with the full Maxwell's
equations and boundary conditions, was proposed. The method took into account magnetic …

This work explores the impact of geometry on viscous electron flow in graphene channels.
We demonstrate that structural modifications of the material edges distinctly influence its …

A non-uniform capacitance profile in the channel of a terahertz (THz) field-effect transistor
(TeraFET) could improve the THz detection performance. The analytical solutions and …

The hydrodynamic behavior of charged carriers leads to nonlinear phenomena such as
solitary waves and shocks, among others. As an application, such waves might be exploited …

We investigate the electron-hole two-stream instability (or Coulomb drag) in bilayer
graphene in the hydrodynamic regime, accounting for the effects of temperature, initial drift …
