TL;DR: In this article, the nonlinear saturation of crossed-beam energy transfer (CBET) for multispeckled laser beams crossing at arbitrary angles is examined using vector particle-in-cell simulations.

TL;DR: In this article, the influence of Coulomb collisions on the dynamics of driven magnetic reconnection in geometry mimicking the Magnetic Reconnection eXperiment (MRX) was investigated using two-dimensional (2D) fully kinetic simulations with a Monte Carlo treatment of the collision operator.

TL;DR: In this article, an analytic theory has been derived for the properties of these solitons that reproduces the behavior observed in kinetic simulations and the experiments at the Trident laser facility, where quasi-monoenergetic ion beams have been obtained from the interaction of an ultraintense, circularly polarized laser with a diamond-like carbon target.

TL;DR: In this paper, the authors demonstrate the ~77× amplification of 0.5 to 3.5-ps pulses of seed light by interaction with Langmuir waves in a low density (1.2 × 1019 cm−3) plasma produced by a 1-ns, 230-J, 1054-nm pump beam with 1.2× 1014 W/cm2 intensity.

TL;DR: This work introduces a class of explicit variational integrators designed to achieve high accuracy for quadratic potentials, with little additional computation relative to traditional integrators, and shows that they improve accuracy for classical biomolecular simulations.
