Gradient Gibbs measures with non-convex potentials and the universality class of the Gaussian Free Field

Simon Buchholz, Codina Cotar, Florian Schweiger

We study a general class of gradient interface models with Hamiltonian $H = β \sum V (\nabla ϕ)$ , $β > 0$ , assuming essentially that the potential $V$ is even, $V^{'} (s) \geq α s$ on $[0,\infty…

Quantitative delocalization for solid-on-solid models at high temperature and arbitrary tilt

Sébastien Ott, Florian Schweiger

We study a family of integer-valued random interface models on the two-dimensional square lattice that include the solid-on-solid model and more generally $p$ -SOS models for $0<p\l…

Tightness of the maximum of Ginzburg-Landau fields

Florian Schweiger, Wei Wu, Ofer Zeitouni

We consider the discrete Ginzburg-Landau field with potential satisfying a uniform convexity condition, in the critical dimension $d = 2$ , and prove that its maximum over boxes of si…
