We propose and analyze a generalized two dimensional XY model, whose interaction
potential has n weighted wells, describing corresponding symmetries of the system. As the …

Semidiscrete modeling of systems of wedge disclinations and edge dislocations via the Airy stress function method

P Cesana, L De Luca, M Morandotti - SIAM Journal on Mathematical Analysis, 2024 - SIAM
We present a variational theory for lattice defects of rotational and translational type. We
focus on finite systems of planar wedge disclinations, disclination dipoles, and edge …

The discrete dislocation dynamics of multiple dislocation loops

S Patrizi, M Vaughan - arxiv preprint arxiv:2406.14793, 2024 - arxiv.org
We consider a nonlocal reaction-diffusion equation that physically arises from the classical
Peierls-Nabarro model for dislocations in crystalline structures. Our initial configuration …

Discrete-to-continuum limits of particles with an annihilation rule

P Van Meurs, M Morandotti - SIAM Journal on Applied Mathematics, 2019 - SIAM

single-species particle systems with singular and nonlocal interactions to particles of …

Discrete-to-continuum convergence of charged particles in 1D with annihilation

P Van Meurs, MA Peletier, N Požár - Archive for Rational Mechanics and …, 2022 - Springer
We consider a system of charged particles moving on the real line driven by electrostatic
interactions. Since we consider charges of both signs, collisions might occur in finite time …

[PDF][PDF] Discrete-to-continuum limits of interacting dislocations

PJP van Meurs - 2015 - research.tue.nl
This thesis studies discrete-to-continuum limits of models for interacting dislocations. This
analysis contributes to the ultimate goal of obtaining a system of equations which accurately …

Γ-convergence analysis for discrete topological singularities: The anisotropic triangular lattice and the long range interaction energy

L De Luca - Asymptotic Analysis, 2016 - journals.sagepub.com
