Abstract
We investigate chiral superconductivity which occurs in the electronic nematic state. A vortex state in a -axis magnetic 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 parameter is positive (negative) and the nematicity is induced along the [110] axis ([100] axis). We discuss nematic-chiral superconductivity in URuSi, SrRuO, and UPt. An experimental test for the examination of nematic order and chiral superconductivity is proposed.
