我们已经找到了半量子涡旋(HQV)的精确稳定区域的超流体$^{3}\text{H}\text{e}\ensuremath{-}A$相限制在一个狭窄的平行板在旋转。标准的Ginzburg-Landau自由能,这是很好地建立,解决了定位由温度$T$和转速$(\ensurmath {\Omega})$跨越的稳定区域。这个$\ensuremath{\Omega}\text{\ensuremath{-}}T$稳定区域足够宽,可以在现有的实验装置中进行实验检查。给出了以${A}{1}$为核心的HQV的详细序参量结构,以解释其相对于其他涡旋或织构稳定性的物理原因。
We have found the precise stability region of the half quantum vortex (HQV) for superfluid $^{3}\text{H}\text{e}\ensuremath{-}A$ phase confined in parallel plates with a narrow gap under rotation. Standard Ginzburg-Landau free energy, which is well established, is solved to locate the stability region spanned by temperature $T$ and rotation speed $(\ensuremath{\Omega})$. This $\ensuremath{\Omega}\text{\ensuremath{-}}T$ stability region is wide enough to check it experimentally in available experimental setup. The detailed order-parameter structure of HQV characterized by ${A}_{1}$ core is given to facilitate the physical reasons of its stability over other vortices or textures.
