Exponential Localization of Spatial Random Permutations in One Dimension

Probability 2026-03-03 v1

Abstract

We consider a class of random permutations of the interval [n,n][-n,n], in which points are typically displaced a distance O(W)O(W). We show the cycles are localized on the scale W3W^3, with an exponentially decaying tail bound. Analogous to eigenfunctions of one dimensional random band matrices, the cycles are conjectured to be localized to the scale W2.W^2.
