Abstract

Fix α>0\alpha>0, then by Fej\'er's theorem (α(logn)Amod1)n1 (\alpha(\log n)^{A}\,\mathrm{mod}\,1)_{n\geq1} is uniformly distributed if and only if A>1A>1. We sharpen this by showing that all correlation functions, and hence the gap distribution, are Poissonian provided A>1A>1. This is the first example of a deterministic sequence modulo one whose gap distribution, and all of whose correlations are proven to be Poissonian. The range of AA is optimal and complements a result of Marklof and Str\"{o}mbergsson who found the limiting gap distribution of (log(n)mod1)(\log(n)\, \mathrm{mod}\,1), which is necessarily not Poissonian.
