Comment on "Self-organized criticality and absorbing states: Lessons from the Ising model"

Abstract

According to Pruessner and Peters [G. Pruessner and O. Peters, Phys. Rev. E 73, 025106(R) (2006)], the finite-size scaling exponents of the order parameter in sandpile models depend on the tuning of driving and dissipation rates with system size. We point out that the same is not true for avalanches in the slow driving limit.
