Theory of p-wave Pairing for 3He on Grafoil
A. V. Chubukov, A. Sokol
Abstract
The specific heat and susceptibility data for 3He on Grafoil are analyzed in the framework of the Landau Fermi liquid theory. The dominant interaction between 3He quasiparticles is found to be in the p-wave channel for most experimentally accessible areal densities of 3He. This interaction is attractive and gives rise to the p-wave transition temperature which for moderate areal densities is estimated to be on the scale of several millikelvin. The relevance of these results to the anomaly in the specific heat observed at Tk = 3.2 \, mK is discussed.
