An experiment to measure the thermal conductivity of polarized liquid 3He

The thermal conductivity of liquid 3He is expected to be sensitive to its nuclear polarization, as the Pauli principle restricts the phase space available for collisions. We demonstrate that a vibrating wire viscometer can be used both as a heater (through viscous heating) and a thermometer to measu...

Summary:The thermal conductivity of liquid 3He is expected to be sensitive to its nuclear polarization, as the Pauli principle restricts the phase space available for collisions. We demonstrate that a vibrating wire viscometer can be used both as a heater (through viscous heating) and a thermometer to measure this thermal conductivity. We report a preliminary experiment on the polarized liquid, which shows an increase of the conductivity upon polarization.
