Claims

C1strongest claim

Momentum-dependent altermagnetic spin splitting suppresses opposite-spin singlet pairing and stabilizes highly anisotropic equal-spin triplet order. In the spin-conserving limit this directional triplet pairing gives rise to nearly dispersionless Majorana boundary states associated with effective one-dimensional topological channels; Rashba spin-orbit coupling drives a mixed-parity state with dispersive Majorana states and spin-resolved boundary spectra that reveal locking between boundary orientation and spin polarization.

C2weakest assumption

The central results rest on a self-consistent mean-field treatment of superconductivity inside a specific two-dimensional d-wave altermagnetic metal model, with an initial spin-conserving limit and a particular form of Rashba spin-orbit coupling added later.

C3one line summary

Altermagnetic spin splitting selects direction-selective triplet pairing in 2D d-wave metals and generates spin-locked Majorana edge states in both spin-conserving and Rashba-mixed regimes.
