通过对含时的Ginzburg-Landau方程的数值和解析研究，我们发现在超流存在下，He-3超流中的涡旋成核是由运动的正常-超流界面的横向不稳定性所主导的。得到了不稳定阈值随超电流密度和波前速度变化的精确表达式。
By numerical and analytical study of the time-dependent Ginzburg-Landau equation we show that vortex nucleation in superfluid He-3 by rapid thermal quench in the presence of superflow is dominated by a transverse instability of the moving normal-superfluid interface. Exact expressions for the instability threshold as a function of supercurrent density and the front velocity are found.
