This work demonstrates the impact of ion-electron collisions on ion transport for strongly inhomogeneous plasmas in the nonlocal regime, where collisionality is insufficient to enforce local thermal equilibrium due to sharp gradients. Ion heat conduction and viscous stress in both unmagnetized and m…

Petrov [Phys. Rev. E 111, 035205 (2025)] has presented an explanation of some parameters of terrestrial gamma-ray flashes within the framework of his model which is based on the assumptions about the formation of surface plasmon waves and the generation of synchrotron radiation due to the interactio…

We investigate magnetohydrodynamic (MHD) turbulence in plane shear flows with a streamwise background magnetic field in the super-Alfvénic regime, i.e., when the flow velocity is larger than the local Alfvén speed. In this regime, turbulence is energetically supplied by large-scale shear of the flow…

Nonthermal power-law spectra with index −2 are ubiquitously observed in turbulent wakefield acceleration, yet their statistical origin remains unresolved. Using one-dimensional particle-in-cell simulations with particle tracking, we analyze the stochastic energy evolution of electrons accelerated by…

Laser-driven ion acceleration offers a promising route toward compact high-energy particle sources, yet achieving control of beam collimation, spectral width, and laser-to-ion energy conversion remains a central challenge for most applications. Using two- and three-dimensional particle-in-cell simul…

Cross-field electron transport in Hall thrusters is widely attributed to high-frequency E×B instabilities, yet its net spatial pathway remains poorly resolved. Here we perform instability-resolving three-dimensional particle-in-cell simulations of a Hall thruster using a boundary-faithful and highly…

Using fully kinetic three-dimensional particle-in-cell (EPOCH) simulations, we investigate resonant planar nanoantenna configurations supporting localized surface plasmon resonances in hydrogen-rich media under irradiation by 795 nm femtosecond laser pulses with intensities of 1017–1019 W/cm2. The s…

Equations describing evolution of the velocity of a rarefied ion beam in a plasma with ion-acoustic turbulence are derived and solved. An ion beam with velocity u greater than the sound speed vs decelerates due to Cherenkov radiation of ion-acoustic waves. Conversely, a beam with u<vs accelerates…

This paper proposes an optimal control strategy to cool an antiproton plasma in a time much shorter than that required by an adiabatic process. The authors examine the length and stability of the plasma, in addition to its duration. The work suggests that optimal control techniques may be useful for experiments with plasmas, in particular with antimatter plasmas, which need to be confined and cooled before significant losses and annihilation occur.

A dusty plasma cloud hosting a counter-rotating vortex lobe pair is driven through controlled neutral-gas pressure ramps spanning nearly an order of magnitude in rate. The transient response is characterized by the longitudinal transport exponents αL and αR, extracted from mean-squared displacements…

We investigate dust-acoustic rogue waves in a one-dimensional binary dusty plasma using analytical nonlinear Schrödinger equation theory and fully kinetic particle-in-cell simulations. Modulational instability initially drives nonlinear focusing and rogue-wave formation, consistent with fluid predic…

Laser wakefield acceleration (LWFA) provides a compact platform for generating bright, ultrashort, and tunable x-ray betatron radiation. When the betatron oscillation wavelength matches the laser centroid oscillation period in a preformed plasma channel, resonance occurs, leading to a rapid amplific…

A key principle underlying most turbulence theories is that the mean energy dissipation rate remains finite even as viscosity vanishes: the so-called zeroth law of turbulence. Although this property has been established for hydrodynamic and magnetohydrodynamic (MHD) turbulence, its validity in weakl…
