EVIDENCE FOR A DIVERGENT SUSCEPTIBILITY AT THE GLASS-TRANSITION

We present evidence for the divergence of the static dielectric susceptibility in liquids as they are supercooled towards T0, the temperature where the dynamics in the liquid come to a halt. This divergence occurs when the width of the imaginary part of the dielectric response approaches a finite limit derivable from a scaling form for the susceptibility. Fits to the temperature dependence of the width indicate that this divergence may occur at T0. © 1995 The American Physical Society.
