Cutoff for a stratified random walk on the hypercube

Probability 2018-09-21 v2

Abstract

We consider the random walk on the hypercube which moves by picking an ordered pair (i,j)(i,j) of distinct coordinates uniformly at random and adding the bit at location ii to the bit at location jj, modulo 22. We show that this Markov chain has cutoff at time 32nlogn\frac{3}{2}n\log n with window of size nn, solving a question posed by Chung and Graham (1997).
