Metastability on the hierarchical lattice
Frank den Hollander, Oliver Jovanovski
We study metastability for Glauber spin-flip dynamics on the -dimensional hierarchical lattice with hierarchical levels. Each vertex carries an Ising spin that can take the…
Multi-colony Wright-Fisher with seed-bank
Giulia Pederzani, Frank den Hollander
We consider a multi-colony version of the Wright-Fisher model with seed-bank that was recently introduced by Blath et al. Individuals live in colonies and change type via resamplin…
Random walks in cooling random environments
L. Avena, F. den Hollander
We propose a model of a one-dimensional random walk in dynamic random environment that interpolates between two classical settings: (I) the random environment is sampled at time ze…
Mixing times of random walks on dynamic configuration models
Luca Avena, Hakan Guldas, Remco van der Hofstad +1
The mixing time of a random walk, with or without backtracking, on a random graph generated according to the configuration model on vertices, is known to be of order .…
Torsional rigidity for regions with a Brownian boundary
Michiel van den Berg, Erwin Bolthausen, Frank den Hollander
Let be the -dimensional unit torus, . The torsional rigidity of an open set is the integral with respect to Lebesgue measure over all starting poin…
Ensemble nonequivalence in random graphs with modular structure
Diego Garlaschelli, Frank den Hollander, Andrea Roccaverde
Breaking of equivalence between the microcanonical ensemble and the canonical ensemble, describing a large system subject to hard and soft constraints, respectively, was recently s…
