Abstract

The early studies of the superfluid phases of3He were marked by often spectacular agreements between theoretical predictions and experimental results. Nevertheless, several experiments have failed to achieve either agreement with the prevailing theory or consistency with each other — and improved experiments do not remove these discrepancies. We will discuss two recent experiments at U.S.C. which indicate that there remain fundamental questions beyond experimental uncertainties. One of these is the stability of superflow in a complex texture in the A-phase. Experimental evidence indicates that superflow may actually be stabilized by the existence of a texture. The other is the long-standing discrepancy between static (SQUID) and dynamic (NMR) measurements of the magnetization discontinuity at the A-B transition. Our recent experiments using a first principles measurement of ΔM support the continued existence of the discrepancy.

    Although the diaphragm is not leak-tight at this thickness, its flow impedance is many orders of magnitude higher than the connecting tubes. Also, the maximum superflow through the diaphragm is negligible.Google Scholar
