Phys. Rev. E 64, 052901 (2001) [4 pages]1/f noise and dynamical heterogeneity in glassesReceived 8 March 2001; published 15 October 2001 We investigate the relationship between two experimental sets of data related to dynamical heterogeneity, the coefficient α of 1/fα dipolar noise derived from the nonexponentiality of the dielectric or magnetic response near and above the mean relaxation time, and the range Δz of the relaxation times. We find that in different classes of glasses, including spin and proton glasses, relaxor materials, and glass-forming liquids, this relationship exhibits the same trend. © 2001 The American Physical Society URL:
