Query: Absence of superdiffusion in the quasiperiodic spin chain at weak
  integrability breaking   There has been interest in the spin transport properties of the
Aubry-Andre-Harper model at high temperatures under weak integrability
breaking, in particular for small interactions or small fields. We present old
unpublished and new results that show that the model is diffusive, meaning that
the claimed superdiffusion [1,2] is a finite-size effect.
