Altermagnetic sublattice order imposes momentum-dependent nodes in the superconducting gap for local pairing interactions and favors nonunitary equal-spin triplet superconductivity at large spin splitting.
Diode efficiency in Rashba superconductors peaks at the Lifshitz transition to strong helical phases with Bogoliubov Fermi surfaces, while Josephson current anisotropy offers a probe for these surfaces in junctions.
