Theory of quantum grid turbulence in superfluid {sup 3}He-B
摘要:
A theory is developed to describe grid turbulence in a superfluid in the case where the normal fluid is held stationary, as would be the case for superfluid He3-B in which the normal fluid is very viscous. The theory is a straightforward development of earlier work, reviewed by Vinen and Niemela [J. Low Temp. Phys. 128, 167 (2002)], and it shows that on large length scales the turbulence is strongly damped by mutual friction. A comparison is made with recent work by Volovik and his colleagues [G. E. Volovik, JETP Lett. 78, 533 (2003); G. E. Volovik, J. Low Temp. Phys. (to be published); and L'vov, Nazarenko, and Volovik, JETP Lett. (to be published)], which was developed while our work was in progress.
