Phys. Rev. Lett. 89, 197202 (2002) [4 pages]Why Temperature Chaos in Spin Glasses Is Hard to ObserveReceived 11 July 2002; published 17 October 2002 The overlap length of a three-dimensional Ising spin glass on a cubic lattice with Gaussian interactions has been estimated numerically by transfer matrix methods and within a Migdal-Kadanoff renormalization group scheme. We find that the overlap length is large, explaining why it has been difficult to observe spin glass chaos in numerical simulations and experiment. © 2002 The American Physical Society URL:
