A modal approach for the solution of the non-linear induction problem in ferromagnetic media

, 2016
The non-linear induction problem in ferromagnetic media is solved using the fixed-point iteration method, where the linearized problem at each iteration is treated by means of a modal approach.

Fourier-transformed gauge theory models of three-dimensional topological orders with gapped boundaries

SciPost Physics
In this paper, we apply the method of Fourier transform and basis rewriting developed in [H. Wang et al., J. High Energy Phys. 02, 030 (2020)] for the two-dimensional quantum double model of topological orders to the three-dimensional gauge theory model (

Fracture initiation in multi-phase materials: a systematic three-dimensional approach using a FFT-based solver

, 2016
This paper studies a two-phase material with a microstructure composed of a hard brittle reinforcement phase embedded in a soft ductile matrix. It addresses the full three-dimensional nature of the microstructure and macroscopic deformation.
