The energy conserving particle-in-cell method [PDF]
Journal of Computational Physics, 2011 A new Particle-in-Cell (PIC) method, that conserves energy exactly, is presented. The particle equations of motion and the Maxwell's equations are differenced implicitly in time by the midpoint rule and solved concurrently by a Jacobian-free Newton Krylov (JFNK) solver.

Particle-In-Cell Simulation Using Asynchronous Tasking [PDF]
, 2021 Recently, task-based programming models have emerged as a prominent alternative among shared-memory parallel programming paradigms. Inherently asynchronous, these models provide native support for dynamic load balancing and incorporate data flow concepts to selectively synchronize the tasks.

Particle in Cell Simulation [PDF]
International Journal of Applied Physics and Mathematics, 2012 Aim of this work is particle system simulation by the new programming language therefore we reviewed several methods for simulation of plasma systems. The particle-in-cell (PIC) method is then applied on a simple plasma system. In the PIC method ions are considered as a neutral-stationary background where electrons move around their initially occupied ...

Numerical investigation of non-linear inverse Compton scattering in double-layer targets
Frontiers in Physics, 2023 Non-linear inverse Compton scattering (NICS) is of significance in laser-plasma physics and for application-relevant laser-driven photon sources. Given this interest, we investigated this synchrotron-like photon emission in a promising configuration ...

Performance Simulation of a 5 kW hall Thruster
Frontiers in Materials, 2021 Hall thruster is a kind of plasma optics device, which is used mainly in space propulsion. To simulate the discharge process of plasma and the performance of a 5 kW hall thruster, a two-dimensional PIC-MCC model in the R-Z plane is built.

Sparse grid reconstructions for Particle-In-Cell methods
ESAIM: Mathematical Modelling and Numerical Analysis, 2022 In this article, we propose and analyse Particle-In-Cell (PIC) methods embedding sparse grid reconstructions such as those introduced in Ricketson and Cerfon [Plasma Phys. Control. Fusion 59 (2017) 024002] and Muralikrishnan et al. [J. Comput. Phys. X 11 (2021) 100094].

Electron mirror instability: particle-in-cell simulations [PDF]
Journal of Plasma Physics, 2018 Properties of the electron mirror instability and its competition with the usually dominant whistler (electron cyclotron) instability driven by the electron perpendicular temperature anisotropy are investigated at the linear level using a Vlasov linear solver and at the nonlinear level using a two-dimensional full particle code.
