Possible high-temperature disorder-induced mobility of solid 4He at T ~ 1.8 K

Abstract

It has been recently reported that there might be supersolidity of 4He around the temperature range: 1.3 K to 1.9 K [A. Eyal, O. Pelleg, L. Embon, E. Polturak, Phys. Rev. Lett. 105, 025301 (2010)]. By treating the solid 4He at very low temperature locally as an amorphous matter and using the transition-rate dependent model together with the specific activation energy and volume, we can observe a series of sudden change of the shearing stresses (which relate to the resistance) at corresponding onset temperatures of supersolid 4He considering the role of holes or defects. We found that the possible supersolidity of 4He might occur at the temperature 1.8 K after intensive calculations,.
