Critical supersaturation of the 3He-4He liquid mixtures at low temperatures

We have investigated the phase separation in supersaturated He-He liquid mixtures due to nucleatio¡¡ via thermal fluctuations below ~ 200 mK and found a large discrepancy in the supersat­uration value between recent experiments (~ 1%) and nucleation theory (~ 10%). We suggest that the rather small d...

Sumario:We have investigated the phase separation in supersaturated He-He liquid mixtures due to nucleatio¡¡ via thermal fluctuations below ~ 200 mK and found a large discrepancy in the supersat­uration value between recent experiments (~ 1%) and nucleation theory (~ 10%). We suggest that the rather small degree of supersaturation found experimentally is due to destabilization of vortices with cores rich in He
