Fixed-magnetization Ising on random graphs up to reconstruction
Reza Gheissari, Will Perkins, Corrine Yap
We study the fixed-magnetization ferromagnetic Ising model on random -regular graphs for and inverse temperature below the tree reconstruction threshold. Our main resul…
Metastability in Glauber dynamics for heavy-tailed spin glasses
Reza Gheissari, Curtis Grant
We study the Glauber dynamics for heavy-tailed spin glasses, in which the couplings are in the domain of attraction of an -stable law for . We show a sharp descripti…
Metastability cascades and prewetting in the SOS model
Reza Gheissari, Eyal Lubetzky
We study Glauber dynamics for the low temperature D Solid-On-Solid model on a box of side-length with a floor at height (inducing entropic repulsion) and a competing…
Diffusions interacting through a random matrix: universality via stochastic Taylor expansion
Amir Dembo, Reza Gheissari
Consider solving a system of stochastic differential equations interacting through a random matrix with independent (not necessarily identic…
Local minima in disordered mean-field ferromagnets
Eric Yilun Song, Reza Gheissari, Charles M. Newman +1
We consider the complexity of random ferromagnetic landscapes on the hypercube given by Ising models on the complete graph with i.i.d. non-negative edge-weights. This…
Nature vs. Nurture: Dynamical Evolution in Disordered Ising Ferromagnets
Lily Z. Wang, Reza Gheissari, Charles M. Newman +1
We study the predictability of zero-temperature Glauber dynamics in various models of disordered ferromagnets. This is analyzed using two independent dynamical realizations with th…
Zero-temperature dynamics in the dilute Curie-Weiss model
Reza Gheissari, Charles M. Newman, Daniel L. Stein
We consider the Ising model on a dense Erdős--Rényi random graph, , with fixed---equivalently, a disordered Curie--Weiss Ising model with $\mbox{Ber}(p)$ cou…
Long-Time Predictability in Disordered Spin Systems Following a Deep Quench
J. Ye, R. Gheissari, J. Machta +2
We study the problem of predictability, or "nature vs. nurture", in several disordered Ising spin systems evolving at zero temperature from a random initial state: how much does th…
Asymptotics of height change on toroidal Temperleyan dimer models
Julien Dubédat, Reza Gheissari
The dimer model is an exactly solvable model of planar statistical mechanics. In its critical phase, various aspects of its scaling limit are known to be described by the Gaussian…
Ising Model: Local Spin Correlations and Conformal Invariance
Reza Gheissari, Clément Hongler, S. C. Park
We study the 2-dimensional Ising model at critical temperature on a simply connected subset of the square grid . The scaling limit of the critical Ising mode…
