Influence of a dc heat flux on the velocity of second sound nearT fλ

Influence of a dc heat flux on the velocity of second sound nearT fλ We have measured the speed of second soundu 2 in He II in the presence of a heat fluxQ. ForT fλ−1 mK>T>T fλ−3.5 mK it is found thatu 2 reduces linearly withQ 2, for 2 mW/cm 2 <Q<6 mW/cm 2 . By extrapolating the data we have deduced that the lambda transition temperature reduces linearly withQ. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Low Temperature Physics Springer Journals

Abstract

We have measured the speed of second soundu 2 in He II in the presence of a heat fluxQ. ForT fλ−1 mK>T>T fλ−3.5 mK it is found thatu 2 reduces linearly withQ 2, for 2 mW/cm 2 <Q<6 mW/cm 2 . By extrapolating the data we have deduced that the lambda transition temperature reduces linearly withQ.
