In anisotropic disordered 2D metals, altermagnetism emerges at zero temperature for larger anisotropy and coupling strengths, competing with ferromagnetism at zero spin-orbit coupling and with a paramagnetic phase at finite spin-orbit coupling via a quantum critical point.
A new equivariant space group framework constructs magnetic Hamiltonians with explicit dependence on magnetic order orientation n, enabling analysis of dynamics-driven topological pumping and ab-initio modeling of real materials.
A weak crystal potential in d-wave altermagnets induces real-space spin quadrupolar order without unit cell enlargement.
