Collisionless energy absorption in the short-pulse intense laser-cluster interaction [PDF]
, 2006 In a previous Letter [Phys. Rev. Lett. 96, 123401 (2006)] we have shown by means of three-dimensional particle-in-cell simulations and a simple rigid-sphere model that nonlinear resonance absorption is the dominant collisionless absorption mechanism in ...

A polynomial particle-in-cell method [PDF]
ACM Transactions on Graphics, 2017 Recently the Affine Particle-In-Cell (APIC) Method was proposed by Jiang et al.[2015; 2017b] to improve the accuracy of the transfers in Particle-In-Cell (PIC) [Harlow 1964] techniques by augmenting each particle with a locally affine, rather than locally constant description of the velocity.

Particle Simulation Model for Self-Field Magnetoplasmadynamic Thruster
Energies, 2019 In order to clarify the discharge principle of the self-field magnetoplasmadynamic thruster (MPDT), a two-dimensional axisymmetric particle-in-cell/Monte Carlo collision (PIC/MCC) model is proposed.

Influence of a power supply model on simulated Hall thruster discharge voltage oscillations
AIP Advances, 2019 Hall thrusters are spacecraft propulsion devices that generate and accelerate plasma to provide thrust. Despite the use of constant voltage supplies to power these devices, complex finite-rate and convective effects lead to significant discharge current ...

Frontiers in Physics, 2018 Owing to their ability to model the physics of low-pressure plasmas away from thermodynamical equilibrium, particle-in-cell (PIC) techniques have become one of the tools of choice to simulate the operation of many plasma devices. This trend is reinforced

Optimal laser focusing for positron production in laser–electron scattering
New Journal of Physics, 2021 Laser–electron beam collisions that aim to generate electron–positron pairs require laser intensities I ≳ 10 ^21 W cm ^−2 , which can be obtained by focusing a 1-PW optical laser to a spot smaller than 10 μ m.
