Preliminary heat capacity measurement of super(3)He in aerogel near its superfluid transition

We report simultaneous heat capacity and torsional oscillator measurement of super(3)He in aerogel near the superfluid transition. The heat capacity has a peak at the temperature T sub(c) where the torsional oscillator shows the onset of superfluid decoupling. The coincidence of these signatures sug...

Zusammenfassung:We report simultaneous heat capacity and torsional oscillator measurement of super(3)He in aerogel near the superfluid transition. The heat capacity has a peak at the temperature T sub(c) where the torsional oscillator shows the onset of superfluid decoupling. The coincidence of these signatures suggests that super(3)He in aerogel does undergo a true thermodynamic transition.
