Flow properties of the axiplanar phase of 3He-A.

Abstract

Because of the recently raised suspicion about the correctness of the conventional (axial) identification of $^{3}\mathit{A}$, we have studied the flow properties of the axiplanar state, the only other possible candidate for the A phase. We show that for small ``planar'' mixture, both phases have very similar flow properties. However, the superflow of the axiplanar phase is always more stable than that of the axial phase, in qualitative (though not yet quantitative) agreement with current experiments. We also propose a method to distinguish these two states clearly using flow experiments.
