在准经典超流费米液体理论的框架下，对超流3 He中孤立涡旋的序参量和自由能进行了弱耦合数值计算.与以前的工作与Ginzburg-Landau理论，我们的结果不限于附近的Tc。我们表明，费米液体效应在较低的温度下起着重要的作用。在高于0.5Tc的蒸气压下，双核涡向A相核涡转变。
We report weak-coupling numerical calculations of the order parameter and the free energy of isolated vortices in superfluid3He in the framework of the quasiclassical theory of superfluid Fermi-liquids. Unlike earlier work with the Ginzburg-Landau theory, our results are not restricted to the vicinity ofTc. We show that Fermi-liquid effects play an important role at lower temperatures. It appears there is a transition from the double core vortex to an A-phase-core vortex at the vapor pressure just above 0.5Tc.
