摘要：

The distribution of thermally excited vortex loops near a superfluid phase transition is calculated. The number density of loops with a given perimeter is found to change from an exponential decay with increasing perimeter to algebraic decay as Tcis approached from below, in agreement with recent simulations of cosmic strings and of the high-Tcsuperconducting transition in zero field. The total line density is calculated and compared with the simulations. A different viewpoint of the Kibble-Zurek scenario for rapidly quenched transitions is proposed, and the role of vortices above the transition temperature is briefly discussed.
