Discontinuous transition in 2D Potts: II. Order-Order Interface convergence

Moritz Dober, Alexander Glazman, Sébastien Ott

The -state Potts model is an archetypical model for various types of phase transitions. We consider it on the square grid and focus on the regime where it undergoes a discontinu…

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 -SOS models for $0<p\l…

Discontinuous transition in 2D Potts: I. Order-Disorder Interface convergence

Moritz Dober, Alexander Glazman, Sébastien Ott

We study a -state Potts model on the square grid when at the point of its (discontinous) transition. This model exhibits exactly extremal Gibbs measures: $q…

A new perspective on the equivalence between Weak and Strong Spatial Mixing in two dimensions

Sébastien Ott

Weak mixing in lattice models is informally the property that ``information does not propagate inside a system''. Strong mixing is the property that ``information does not propagat…

Relaxation time and topology in 1D models

Pietro Caputo, Sébastien Ott, Assaf Shapira

We discuss the relaxation time (inverse spectral gap) of the one dimensional model, for all and with two types of boundary conditions. We see how its low temperature asy…
