Metric Poissonian pair correlation for real sequences and energy estimates

Abstract: In this paper, we establish new conditions under which a sequence of real numbers has metric Poissonian pair correlation. Our conditions improve upon results of Aistleitner, El-Baz and Munsch, and resolve one of their open problems for sequences that grow faster than a quadratic polynomial. As applications, we show that quantitatively convex and polynomial sequences are metric Poissonian.
