Pressure induced flow of solid 4He

Recent torsional oscillator measurements on solid He-4 in the pores of Vycor and in bulk have demonstrated non-classical rotational inertia, interpreted in terms of a transition to a supersolid phase. In the interest of determining whether or not solid He-4 exhibits any of the other unusual flow properties of a superfluid, we have used a piezoelectrically driven diaphragm to study the pressure-induced flow of solid helium into the Vycor pores. We also present preliminary results of the pressure-induced flow of bulk solid helium through an array of microchannels.
