On reversing the Simon-Lieb inequality in high-dimensional percolation

Romain Panis, Bruno Schapira

We study Bernoulli percolation on in dimensions . We prove that a classical consequence of the van den Berg-Kesten inequality, often referred to as the Simon-L…

A random walk approach to high-dimensional critical phenomena

Hugo Duminil-Copin, Aman Markar, Romain Panis +1

We present a "black box" proof of mean-field near-critical behaviour for a family of functions on () satisfying a short list of assumptions. The functions repr…

Sharp bounds on the half-space two-point function for high-dimensional Bernoulli percolation

Romain Panis, Bruno Schapira

We consider Bernoulli percolation on with . We prove an up-to-constant estimate for the critical two-point function restricted to a half-space. This completes pr…

One-arm exponents of the high-dimensional Ising model

Diederik van Engelenburg, Christophe Garban, Romain Panis +1

We study the probability that the origin is connected to the boundary of the box of size (the one-arm probability) in several percolation models related to the Ising model. We…

The incipient infinite cluster of the FK-Ising model in dimensions and the susceptibility of the high-dimensional Ising model

Romain Panis

We consider the critical FK-Ising measure on with . We construct the measure $ϕ^\infty:=\lim_{|x|\rightarrow \infty}ϕ_{β_c}[\:\cdot\: |\: 0\le…

One-arm exponents of high-dimensional percolation revisited

Diederik van Engelenburg, Christophe Garban, Romain Panis +1

We consider sufficiently spread-out Bernoulli percolation in dimensions . We present a short and simple proof of the up-to-constants estimate for the one-arm probability in…
