IWCN 2021: A Practical Peierls Phase Recipe for Periodic Atomistic Systems Under Magnetic Fields
Online Presentations | 14 Jul 2021 | Contributor(s):: Alessandro Cresti
In this contribution I will provide general ready-to-use formulas to determine Peierls phase factors that preserve the translation symmetry of any periodic quasi-one-dimensional or two-dimensional system under a homogeneous magnetic field.

Nonlinear Quantum Electrodynamics in Dirac Materials
Online Presentations | 29 Apr 2021 | Contributor(s):: Yuli Lyanda-Geller
We show that similar nonlinear effects arise in Dirac materials at much lower fields, the magnitude of the effects is significant, and they can be observed in laboratory experiments. We predict and calculate the nonlinear electromagnetic effects and discuss compounds where the nonlinear...

Least-Squares Finite Element Method and Nested Iteration for Electromagnetic Two-Fluid Plasma Models
Online Presentations | 04 Feb 2016 | Contributor(s):: Christopher Leibs
Efforts are currently being directed towards a fully implicit, electromagnetic, JFNK-based solver, motivating the necessity of developing a fluid-based, electromagnetic, preconditioning strategy [1]. The two-fluid plasma (TFP) model is an ideal approximation to the kinetic Jacobian. The TFP model...

Application of Multigrid Techniques to Magnetic and Electromagnetic Systems
Online Presentations | 04 Feb 2016 | Contributor(s):: Benjamin Cowan
We discuss the use of multigrid techniques for several novel systems related to electromagnetics. One of these is the magnetostatic problem, in which systems can involve highly anisotropic and nonlinear materials. We describe the linear problems arising in several variations of this problem,...
