    Abstract

    We calculate the temperature T and angular (.,.) dependencies of the upper critical induction B-c2(theta, phi, 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 (SK) state B-c2(theta, phi, T) exceeds that of the chiral Anderson-BrinkmanMorel ( ABM) state and exhibits a kink at theta =theta*(T, phi), indicative of a first-order transition from its chiral, nodal-direction behavior to its non-chiral, antinodal-direction behavior. Applicabilities to Sr2RuO4, UCoGe and the candidate topological superconductor CuxBi(2)Se(3) are discussed.
