Query: The spectrum of the abelian sandpile model   In their previous work, the authors studied the abelian sandpile model on
graphs constructed from a growing piece of a plane or space tiling, given
periodic or open boundary conditions, and identified spectral factors which
govern the asymptotic spectral gap and asymptotic mixing time. This article
gives a general method of determining the spectral factor either
computationally or asymptotically and performs the determination in specific
examples.
