Slow 4He quenches produce fuzzy, transient vortices
1Blackett Laboratory, Imperial College, London SW7 2BZ, United Kingdom.
Abstract:
We examine the Zurek scenario for the production of vortices in quenches of liquid 4He in the light of recent experiments. Extending our previous results to later times, we argue that short wavelength thermal fluctuations make vortices poorly defined until after the transition has occurred. Further, if and when vortices appear, it is plausible that they will decay faster than anticipated from turbulence experiments, irrespective of quench rates.
