Jump processes as generalized gradient flows

MA Peletier, R Rossi, G Savaré, O Tse - Calculus of Variations and Partial …, 2022 - Springer
We have created a functional framework for a class of non-metric gradient systems. The
state space is a space of nonnegative measures, and the class of systems includes the …

Nonsingular stress distribution of edge dislocations near zero-traction boundary

H Shima, T Sumigawa, Y Umeno - Materials, 2022 - mdpi.com
Among many types of defects present in crystalline materials, dislocations are the most
influential in determining the deformation process and various physical properties of the …

Elasto-plastic evolution of single crystals driven by dislocation flow

T Hudson, F Rindler - Mathematical Models and Methods in Applied …, 2022 - World Scientific
This work introduces a model for large-strain, geometrically nonlinear elasto-plastic
dynamics in single crystals. The key feature of our model is that the plastic dynamics are …

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 …

Homogenization of elasto-plastic evolutions driven by the flow of dislocations

P Bonicatto, F Rindler - arXiv preprint arXiv:2410.02906, 2024 - arxiv.org
Starting from a prototypical model of elasto-plasticity in the small-strain and quasi-static
setting, where the evolution of the plastic distortion is driven exclusively by the motion of …

Global existence and mean-field limit for a stochastic interacting particle system of signed Coulomb charges

P van Meurs, MA Peletier, T Slangen - arXiv preprint arXiv:2410.15855, 2024 - arxiv.org
We study a system of stochastic differential equations with singular drift which describes the
dynamics of signed particles in two dimensions interacting by the Coulomb potential. In …

Quantitative estimate of the continuum approximations of interacting particle systems in one dimension

M Kimura, P van Meurs - SIAM Journal on Mathematical Analysis, 2021 - SIAM
We consider a large class of interacting particle systems in one dimension described by an
energy whose interaction potential is singular and nonlocal. This class covers Riesz gases …

Boundary-layer analysis of repelling particles pushed to an impenetrable barrier

P van Meurs - SIAM Journal on Mathematical Analysis, 2022 - SIAM
This paper considers the equilibrium positions of n particles in one dimension. Two forces
act on the particles; a nonlocal repulsive particle-interaction force and an external force …
