Cutoff for non-negatively curved Markov chains

J Salez - Journal of the European Mathematical Society, 2023 - ems.press
Abstract Discovered by Aldous, Diaconis and Shahshahani in the context of card shuffling,
the cutoff phenomenon has since then been established for a variety of Markov chains …

Spatial mixing and the random‐cluster dynamics on lattices

R Gheissari, A Sinclair - Random Structures & Algorithms, 2024 - Wiley Online Library
An important paradigm in the understanding of mixing times of Glauber dynamics for spin
systems is the correspondence between spatial mixing properties of the models and bounds …

Random-cluster dynamics on random regular graphs in tree uniqueness

A Blanca, R Gheissari - Communications in Mathematical Physics, 2021 - Springer
We establish rapid mixing of the random-cluster Glauber dynamics on random\varDelta Δ-
regular graphs for all q ≥ 1 q≥ 1 and p< p_u (q,\varDelta) p< pu (q, Δ), where the threshold …

Asymptotic stability and cut-off phenomenon for the underdamped Langevin dynamics

S Lee, M Ramil, I Seo - arXiv preprint arXiv:2311.18263, 2023 - arxiv.org
In this article, we provide detailed analysis of the long-time behavior of the underdamped
Langevin dynamics. We first provide a necessary condition guaranteeing that the zero-noise …

Sampling from Potts on random graphs of unbounded degree via random-cluster dynamics

A Blanca, R Gheissari - The Annals of Applied Probability, 2023 - projecteuclid.org
We consider the problem of sampling from the ferromagnetic Potts and random-cluster
models on a general family of random graphs via the Glauber dynamics for the random …

Cutoff for the Glauber-Exclusion process in the full high-temperature regime: an information percolation approach

HQ Tran - arXiv preprint arXiv:2310.15810, 2023 - arxiv.org
The Glauber-Exclusion process is a superposition of a Glauber dynamics and the Symmetric
Simple Exclusion Process (SSEP) on the lattice. The model was shown to admit a reaction …

Random-cluster dynamics in : Rapid mixing with general boundary conditions

A Blanca, R Gheissari, E Vigoda - 2020 - projecteuclid.org
The random-cluster model with parameters (p,q) is a random graph model that generalizes
bond percolation (q=1) and the Ising and Potts models (q≧2). We study its Glauber …

The shuffle block dynamics

E Nestoridi, A Priestley, D Schmid - arXiv preprint arXiv:2304.02588, 2023 - arxiv.org
We introduce and analyze the $ S_k $ shuffle on $ N $ cards, a natural generalization of the
celebrated random adjacent transposition shuffle. In the $ S_k $ shuffle, we choose …

Cutoff phenomenon for some interacting particle systems

HQ Tran - 2024 - theses.hal.science
On a finite state space, an irreducible continuous-time Markov chain converges to its unique
stationary measure, or in other words, mixes. The convergence is often measured by the …
