Extended s-wave altermagnets
read the original abstract
We propose extended s-wave altermagnets (sAMs) as a class of magnetic states which are fully gapped, spin-compensated, and feature spin-polarized bands. sAMs are formed through valley-exchange symmetries, which act as momentum-space translations beyond standard crystallographic spin-group classifications. Using an effective two-valley model, we demonstrate that sAMs exhibit isotropic spin splitting, enable spin-selective transport in tailored heterostructures, and give rise to descendant pair density wave order. From a microscopic sAM minimal model, we develop the guiding principles to identify sAMs in quantum magnets.

Light-Induced Even-Wave Spin Splittings in Nonmagnetic Centrosymmetric Systems with Spin-Orbit Coupling
Circularly polarized light induces even-wave spin splittings in nonmagnetic centrosymmetric systems with SOC, producing s-, d-, and g-wave patterns like those in ferromagnets and enabling Chern insulator phases.

Altermagnons at the metal-insulator transition
Slave-boson calculations on the checkerboard Hubbard model show altermagnons crossing from chirality-selective dissipation to coherent but deformed chiral branches at the metal-insulator transition.
