Nonlinear dielectric properties of glasses at low temperatures

Disordered dielectrics exhibit a variety of nonlinear responses at temperatures below 4 K, sometimes in remarkably small fields. Four characteristic types of behaviour are identified. Two of these are well understood in terms of the `standard′; two-level system model, but two require further experimental study and theoretical development. One type is similar to piezoelectric ceramic behaviour.
