Abstract
Thermal nucleation of kink-antikink pairs in an elastic string subject ed to a washboard potential is analyzed in the classical limit at low temperature. The nucleation rate is calculated analytically for values of the tilt up to close the instability threshold. Numerical simulati on is shown to support our predictions in the diverse parameter regime s. (C) 1998 Elsevier Science B.V. All rights reserved.
