Upper tails for irregular graphs beyond the mean-field regime

Asaf Cohen Antonir, Matan Harel, Frank Mousset +1

Let $G_{n, p}$ be the binomial random graph of density $p$ and let $X_{H}$ be the number of copies of a fixed graph $H$ in $G_{n, p}$ . We prove asymptotically tight bounds on the logar…

Planar percolation and the loop O(n) model

Alexander Glazman, Matan Harel, Nathan Zelesko

We show that a large class of site percolation processes on any planar graph contains either zero or infinitely many infinite connected components. The assumptions that we require…

Upper tails for arithmetic progressions revisited

Matan Harel, Frank Mousset, Wojciech Samotij

Let $X$ be the number of $k$ -term arithmetic progressions contained in the $p$ -biased random subset of the first $N$ positive integers. We give asymptotically sharp estimates on th…

Quantitative disorder effects in low-dimensional spin systems

Paul Dario, Matan Harel, Ron Peled

The Imry-Ma phenomenon, predicted in 1975 by Imry and Ma and rigorously established in 1989 by Aizenman and Wehr, states that first-order phase transitions of low-dimensional spin…

Macroscopic loops in the loop O(n) model via the XOR trick

Nicholas Crawford, Alexander Glazman, Matan Harel +1

The loop $O (n)$ model is a family of probability measures on collections of non-intersecting loops on the hexagonal lattice, parameterized by a loop-weight $n$ and an edge-weight $…
