Abstract
We show that nucleation of vortex loops in superfluid He-3 by rapid thermal quench in the presence of superflow is dominated by a transverse instabili ty of the moving normal-superfluid interface. Exact expressions for the ins tability threshold as a function of supercurrent density and the front velo city are found. The results are verified by numerical solution of the Ginzb urg-Landau equation. (C) 2000 Elsevier Science B.V.
