Overview

The study uncovers novel superconductivity phenomena in altermagnets, suggesting unique implications for quantum materials.

Key Points

  • The research reveals multiple exotic superconducting states in altermagnets, including a non-unitary superconductor.
  • Significant findings include a fractional ac Josephson current, particularly affecting one spin polarization.
  • Using fundamental symmetry perspectives, the study tabulates all symmetry-allowed pairing functions in altermagnets.
  • Ginzburg-Landau theories indicate these superconductors reach stable minima, highlighting their topological characteristics.
