我们提出了一种简单的方法来稳定超导Ruthenate中的半量子涡旋，假定序参数具有手征p(X)+ip(Y)对称性，正如最近的实验所建议的那样。该方法首先由Salomaa和Volovik在氦-3的背景下给出，非常自然地适合于具有层状、准二维钙钛矿晶体结构的Ruthenate锶。我们提出了可能的实验来检测它们的非阿贝尔编织统计。这些实验对拓扑量子计算具有潜在的重要意义。
We propose a simple way to stabilize half-quantum vortices in superconducting strontium ruthenate, assuming the order parameter is of chiral p(x)+ip(y) symmetry, as is suggested by recent experiments. The method, first given by Salomaa and Volovik in the context of Helium-3, is very naturally suited for strontium ruthenate, which has a layered, quasi-two-dimensional, perovskite crystal structure. We propose possible experiments to detect their non-Abelian braiding statistics. These experiments are of potential importance for topological quantum computation.
