本文研究了电子处于基态时的手征超导电性。本文在向列型手征超导体的两分量Ginzburg-Landau模型的基础上，研究了磁场中的涡旋态。结果表明，在超导体中，向列性和手征性的非平凡合作稳定了各种涡旋晶格结构。特别是当平方各向异性参数为正（负）且沿着[110]轴（[100]轴）诱导向列性时，发生涡旋晶格结构转变。我们讨论了向列-手征超导电性。本文提出了一个检验超导电性的实验方法。
We investigate chiral superconductivity which occurs in the electronic nematic state. A vortex state in amagnetic field is studied on the basis of the two-component Ginzburg-Landau model for nematic-chiral superconductors. It is shown that various vortex lattice structures are stabilized by nontrivial cooperation of nematicity and chirality in superconductors. In particular, the vortex lattice structural transition occurs when a square anisotropy parameteris positive (negative) and the nematicity is induced along the [110] axis ([100] axis). We discuss nematic-chiral superconductivity in,, and. An experimental test for the examination of nematic order and chiral superconductivity is proposed.
