Anti-spin Laue groups: classification of anti-altermagnets and their representative minimal models
Colin Lange, Rodrigo Jaeschke-Ubiergo, Alexander Mook +1
Anti-altermagnets exhibit odd-parity nonrelativistic spin splitting, yet unlike even-parity altermagnets, their momentum-space symmetries lack a reduced classification analogous to…

Emergent altermagnetism at surfaces of antiferromagnets: full symmetry classification and material identification
Colin Lange, Rodrigo Jaeschke-Ubiergo, Atasi Chakraborty +4
We demonstrate the emergence of altermagnetism at the surfaces of antiferromagnets, vastly expanding the number of material candidates with altermagnetic characteristics and establ…
