Journal ArticleDOI
The critical curves of the random pinning and copolymer models at weak coupling
TL;DR: In this paper, the authors studied random pinning and copolymer models with a polynomial tail with finite mean and proved a conjecture of Bolthausen, den Hollander and Opoku.
Journal ArticleDOI
Quenched central limit theorems for random walks in random scenery
TL;DR: In this paper, it is shown that under suitable assumptions on the random walk S and the random scenery ω, almost surely with respect to ω, the correctly renormalized sequence (Z n ) n ≥ 1 is proved to converge in distribution to a centered Gaussian law with explicit variance.
Journal ArticleDOI
Asymptotics of the critical time in Wiener sausage percolation with a small radius
Dirk Erhard,Julien Poisat +1 more
TL;DR: In this paper, the authors consider a continuum percolation model on a set of independent Wiener sausages and derive moment estimates on the capacity of Wiener SAusages.
Journal ArticleDOI
Random pinning model with finite range correlations: Disorder relevant regime
TL;DR: In this article, the authors extended the results on disorder relevance obtained for the random pinning model with i.i.d disorder to the model with finite range correlated disorder, where annealed and quenched critical points differ.
Journal ArticleDOI
On quenched and annealed critical curves of random pinning model with finite range correlations
TL;DR: In this article, the critical curve of the annealed model can be expressed in terms of the Perron-Frobenius eigenvalue of an explicit transfer matrix.
