Direct nanoscopic observation of plasma waves in the channel of a graphene field-effect transistor [PDF]
Light Sci Appl, 2020 Plasma waves play an important role in many solid-state phenomena and devices. They also become significant in electronic device structures as the operation frequencies of these devices increase.

BO: A unified tool for plasma waves and instabilities analysis [PDF]
Computer Physics Communications, 2019 A unified numerically solvable framework for dispersion relations with arbitrary number of species drifting at arbitrary directions and with Krook collision is derived for linear uniform/homogenous kinetic plasma, which largely extended the standard one [

Relativistic self focusing and frequency shift of super-Gaussian laser beam in plasma
Results in Physics, 2020 Relativistic self focusing and frequency shift of laser beam having super-Gaussian profile in space and Gaussian profile in time is studied in a plasma. The relativistic mass nonlinearity is found to cause time dependent self focusing of the laser pulse ...

Nonlinear plasma wave in magnetized plasmas [PDF]
Physics of Plasmas, 2013 Nonlinear axisymmetric cylindrical plasma oscillations in magnetized collisionless plasmas are a model for the electron fluid collapse on the axis behind an ultrashort relativisically intense laser pulse exciting a plasma wake wave. We present an analytical description of the strongly nonlinear oscillations showing that the magnetic field prevents ...

Direct Observation of Plasma Waves and Dynamics Induced by Laser-Accelerated Electron Beams [PDF]
Physical Review X, 2018 Plasma wakefield acceleration (PWFA) is a novel acceleration technique with promising prospects for both particle colliders and light sources. However, PWFA research has so far been limited to a few large-scale accelerator facilities worldwide.

Kinetic simulations of ladder climbing by electron plasma waves. [PDF]
Physical Review E, 2017 The energy of plasma waves can be moved up and down the spectrum using chirped modulations of plasma parameters, which can be driven by external fields. Depending on whether the wave spectrum is discrete (bounded plasma) or continuous (boundless plasma),

Space Weather, 2023 It is believed that galactic cosmic rays and solar energetic particles are the two major sources of ionizing radiation. However, the radiation source may also be due to relativistic electrons that are associated with precipitation from the Van Allen ...

Second-order perturbations in Alfvén waves in finite pressure plasma
Solar-Terrestrial Physics, 2022 It is shown first that in finite pressure plasma, just as in cold plasma, Alfvén waves created by an initial perturbation generate plasma flows and decreases in the magnetic field, which propagate along with these waves.

Discussion on Rayleigh equation obtained for a Hall thruster plasma with dust
Journal of Theoretical and Applied Physics, 2018 The present study focuses on the Rayleigh equation derived in the case of a Hall thruster plasma having dust contamination, produced near the exit of the channel due to the finite divergence of the accelerated ions and the sputtering of the walls. In the
