Energetic spectra from semi-implicit particle-in-cell simulations of magnetic reconnection [PDF]

open access: yesScientific Reports
Astrophysical observations suggest that magnetic reconnection in relativistic plasmas plays an important role in the acceleration of energetic particles. Modeling this accurately requires numerical schemes capable of addressing large scales and realistic

Particle Acceleration in Mildly Relativistic Outflows of Fast Energetic Transient Sources

open access: yesUniverse, 2022
Recent discovery of fast blue optical transients (FBOTs)—a new class of energetic transient sources—can shed light on the long-standing problem of supernova—long gamma-ray burst connections.

Non-harmonic response of relativistic particle to driving harmonic force

open access: yesRevista Brasileira de Ensino de Física, 2023
We consider the properties of one-dimensional oscillations of a relativistic particle under a driving harmonic force. It is found that in the general case the speed oscillations are an infinite sum of odd sinusoidal and even cosinusoidal waves.

Asymptotic velocity of relativistic E × B drift

open access: yesAIP Advances, 2021
We have obtained the asymptotic velocity of a relativistic charged particle in static and uniform electric and magnetic fields with arbitrary orientations of the fields and with an arbitrary ratio of a = |E|/|B|, where the particle is assumed highly ...

Super-radiance from a relativistic source

open access: yesNew Journal of Physics, 2023
Cooperative super-radiant emission from a highly relativistic multi-particle source is modeled and solved for the simple case of two particles. An existing model of a single relativistic two-level particle is used to construct a Hamiltonian describing ...

Quasi-relativistic description of a quantum particle moving through one-dimensional piecewise constant potentials

open access: yesResults in Physics, 2020
Using a novel quasi-relativistic wave equation, which can give precise results up to energies ~mc2, exact quantum mechanical solutions are found which corresponds to a particle with mass moving through one-dimensional piecewise constant potentials.

Particle Acceleration in Relativistic Outflows [PDF]

open access: yesSpace Science Reviews, 2012
In this review we confront the current theoretical understanding of particle acceleration at relativistic outflows with recent observational results on various source classes thought to involve such outflows, e.g. gamma-ray bursts, active galactic nuclei, and pulsar wind nebulae.

Relativistic particle scattering [PDF]

open access: yesCommunications in Mathematical Physics, 1985
In the presence of competing relativistic formalisms for interacting particle dynamics, a model-independent axiomatic approach is proposed for the study of the following asymptotic aspects of relativistic classical particle dynamics: the definition of the scattering operator, scattering angle and time-delay, and the specification of a general ...
