Given an α> 1 and a θ with unbounded continued fraction entries, we characterize new relations between Sturmian subshifts with slope θ with respect to (i) an α-Hölder regularity condition of a spectral metric,(ii) level sets defined in terms of the Diophantine properties of θ, and (iii) complexity notions which we call αrepetitiveness, α-repulsiveness and α-finiteness—generalizations of the properties known as linear repetitiveness, repulsiveness and power freeness, respectively. We show that the level sets relate naturally to (exact) Jarnık sets and prove that their Hausdorff dimension is 2/(α+ 1).1. Introduction and outline 1.1. Introduction. Links between regularity of spectral metrics built from noncommutative representations (spectral triples) and aperiodic behaviour of Sturmian subshifts, in the case where the continued fraction entries of the slope are bounded, were first observed in [39]. We show new relations between regularity properties of spectral metrics of Sturmian subshifts (where the continued fraction entries of the slopes are unbounded), fractal level sets (defined in terms of the Diophantine properties of θ) and
