Abstract

We calculate the temperature $T$ and angular $(θ, ϕ)$ dependence of the upper critical induction $B_{c 2} (θ, ϕ, T)$ for parallel-spin superconductors with an axially symmetric $p$ -wave pairing interaction pinned to the lattice and a dominant ellipsoidal Fermi surface (FS). For all FS anisotropies, the chiral Scharnberg-Klemm state $B_{c 2} (θ, ϕ, T)$ exceeds that of the chiral Anderson-Brinkman-Morel state, and exhibits a kink at $θ = θ^{*} (T, ϕ)$ , indicative of a first-order transition from its chiral, nodal-direction behavior to its non-chiral, antinodal-direction behavior. Applicability to Sr $_{2}$ RuO $_{4}$ , UCoGe, and topological superconductors such as Cu $_{x}$ Bi $_{2}$ Se $_{3}$ is discussed.
