Hydrodynamical behavior for the symmetric simple partial exclusion with open boundary

C Franceschini, P Gonçalves, B Salvador - Mathematical Physics, Analysis …, 2023 - Springer
We analyze the symmetric simple partial exclusion process, which allows at most α particles
per site, and we put it in contact with stochastic reservoirs whose strength is regulated by a …

Linear and Nonlinear Fractional PDEs from interacting particle systems

P Cardoso, P Gonçalves - arxiv preprint arxiv:2407.02246, 2024 - arxiv.org
In these notes, we describe the strategy for the derivation of the hydrodynamic limit for a
family of long range interacting particle systems of exclusion type with symmetric rates. For …

Derivation of the fractional porous medium equation from a microscopic dynamics

P Cardoso, R De Paula, P Gonçalves - Nonlinearity, 2023 - iopscience.iop.org
In this article we derive the fractional porous medium equation for any power of the fractional
Laplacian as the hydrodynamic limit of a microscopic dynamics of random particles with long …

Hydrodynamics for the ABC model with slow/fast boundary

P Gonçalves, R Misturini, A Occelli - Stochastic Processes and their …, 2023 - Elsevier
In this article, we consider the ABC model in contact with slow/fast reservoirs. In this model,
there is one particle per site, which can be of type α∈{A, B, C} and particles exchange …

Bootstrap percolation and kinetically constrained models: two-dimensional universality and beyond

I Hartarsky - 2022 - theses.hal.science
We study two tightly related classes of statistical mechanics models on the two-dimensional
square lattice—kinetically constrained models and bootstrap percolation. The former arose …

Hydrodynamics for SSEP with non-reversible slow boundary dynamics: Part I, the critical regime and beyond

C Erignoux, P Gonçalves, G Nahum - Journal of Statistical Physics, 2020 - Springer
The purpose of this article is to provide a simple proof of the hydrodynamic and hydrostatic
behavior of the SSEP in contact with slowed reservoirs which inject and remove particles in …

From exclusion to slow and fast diffusion

P Gonçalves, G Nahum, M Simon - arxiv preprint arxiv:2301.06585, 2023 - arxiv.org
We construct a nearest-neighbour interacting particle system of exclusion type, which
illustrates a transition from slow to fast diffusion. More precisely, the hydrodynamic limit of …

Energy estimates and convergence of weak solutions of the porous medium equation

R De Paula, P Gonçalves, A Neumann - Nonlinearity, 2021 - iopscience.iop.org
We study the convergence of the weak solution of the porous medium equation with a type
of Robin boundary conditions, by tuning a parameter either to zero or to infinity. The …

[PDF][PDF] Quarter-Sweep Successive Over-relaxation Approximation to the Solution of Porous Medium Equations.
