An Effective Theory of Superfluid Turbulence from Local Scale Invariance | | Siddhartha Sen
; Koushik Ray
; | | Date: |
20 May 2011 | | Abstract: | An effective locally scale invariant model is constructed using Weyl’s method
starting from a free Schroedinger equation. The model requires additional gauge
and gravitational degrees of freedom. It is suggested that this scale invariant
model is an effective theory for superfluid turbulence. The additional degrees
of freedom introduced can then be identified with filament excitations or zeros
of a Gross-Pitaevski equation which are used to describe superfluid turbulence.
Qualitative estimates of the way filaments separate after collision are made
which agree with observations. | | Source: | arXiv, 1105.4056 | | Services: | Forum | Review | PDF | Favorites | |
