Quasi-arithmetic sequences have no Poissonian pair correlation conjecture

Let (an)n≥1\left(a_n\right)_{n\geq 1} be a strictly increasing sequence of positive integers. It is quasi-arithmetic of degree dd if there exist constants C,K>0C,K>0 and a strictly increasing sequence (Ni)i≥1\left(N_i\right)_{i\geq 1} of positive integers such that, for every i≥1i\geq 1, some subset A(i)⊂(an)1≤n≤NiA^{(i)}\subset\left(a_n\right)_{1\leq n\leq N_i} with ∣A(i)∣≥CNi\left|A^{(i)}\right|\geq CN_i is contained in a dd-dimensional arithmetic progression of size at most KNiKN_i, where dd is a positive integer. The quasi-arithmetic non-Poissonian pair correlation conjecture. If (an)n≥1\left(a_n\right)_{n\geq 1} is quasi-arithmetic of some degree dd, then there is no α\alpha such that the pair correlation of ({anα})n≥1\left(\left\{a_n\alpha\right\}\right)_{n\geq 1} is Poissonian.

The paper states that this is equivalent to the maximal-additive-energy formulation because a sequence has additive energy E(AN)=Ω(N3)E(A_N)=\Omega(N^3) if and only if it is quasi-arithmetic of some degree. It strengthens the known full-measure result to exclude every value of α\alpha.
