Phys. Rev. Lett. 42, 1212–1215 (1979)Critical Behavior of the Penetration Length of a Vortex into a Subcritical RegionReceived 3 January 1979; published in the issue dated 30 April 1979 I have measured the penetration length ξ of a vortex into a subcritical region, using the electroconvective instability in a liquid crystal. ξ corresponds to the correlation length of the order-parameter fluctuations in a second-order phase transition and is found to have a mean-field behavior. Moreover, I have found a new effect: propagation of solitary vortices over a distance equal to that correlation length. © 1979 The American Physical Society URL:
