Abstract
We calculate the thermal diffusivity D = κ/cρ and butterfly velocity vB in holographic models that flow to AdS2 × Rd fixed points in the infra-red. We show that both these quantities are governed by the same irrelevant deformation of AdS2 and hence establish a simple relationship between them. When this deformation corresponds to a universal dilaton mode of dimension Δ = 2 then this relationship is always given by D = vB2/(2πT).
