Checkerboard-lattice Hubbard electrons are unstable to weak-coupling altermagnetism whose magnons display alternating chirality splitting.
Extends density-matrix kinetic theory beyond non-crossing approximation to fourth-order disorder, yielding extrinsic tau^0 contributions to anomalous Hall conductivity in the 2D Dirac model.
Symmetry analysis predicts anisotropic thermomagnonic torques in insulating altermagnets that induce domain-wall precession and direction-selective skyrmion motion under temperature gradients.
A weak crystal potential in d-wave altermagnets induces real-space spin quadrupolar order without unit cell enlargement.
