We construct one-dimensional potentials V (x) so that if H = ? d 2 dx 2 + V (x) on L 2 (R), then H has purely singular spectrum; but for a dense set D, ' 2 D implies that j(';e ?itH ')j C ' jtj ?1=2 ln(jtj) for jtj > 2. This implies the spectral measures have Hausdorr dimension one and also, following an idea of Malozemov-Molchanov, provides counterexamples to the direct extension of the theore...
