Abstract We study the regularity of spectral measures of dynamical systems arising from a translation action on tilings of substitutive nature. The results are inspired by the work of Bufetov and Solomyak 8, where they established a log-Hölder modulus of continuity of one-dimensional self-similar tiling systems. We generalize this result to higher dimensions in the more general setting of self-affine tilings systems. Further analysis leads to uniform estimates in the whole space of spectral parameters, allowing to deduce logarithmic rates of weak mixing.
Juan Marshall‐Maldonado (Mon,) studied this question.
