Abstract

Recent theoretical attempts to explain the observed vortex-core phase transition in superfluid B3 yield conflicting results. Variational calculations by Fetter and Theodrakis, based on realistic strong-coupling parameters, yield a phase transition in the Ginzburg-Landau region that is in qualitative agreement with the phase diagram. Numerically precise calculations by Salomaa and Volivil (SV), based on the Brinkman-Serene-Anderson (BSA) parameters, do not yield a phase transition between axially symmetric vortices. The ambiguity of these results is in part due to the large differences between the parameters, which are inputs to the vortex free-energy functional. We comment on the relative merits of the parameters based on recent improvements in the quasiparticle scattering amplitude and the BSA parameters used by SV.
