SUMMARY:Vortex stretching as a mechanism for quantum kinetic energy decay 
 - Bob Kerr (University of Warwick)
DTSTART:20101203T160000Z
DTEND:20101203T170000Z
UID:TALK27009@talks.cam.ac.uk
CONTACT:Dr C. P.  Caulfield
DESCRIPTION:For a pair of perturbed anti-parallel quantum vortices\, kinet
 ic energy\n$K_{\\nabla\\psi}$ is converted into interaction energy $E_I$ l
 eading to\nlocal kinetic energy depletion that is analogous to energy deca
 y in a\nclassical fluid\, even though the governing equations are Hamilton
 ian and\nenergy conserving. The intermediate stages include: the generatio
 n of\nvortex waves\, their deepening\, multiple reconnections\, the emissi
 on of\nvortex rings and phonons and the creation of a -5/3 kinetic energy\
 nspectrum.
