Magnetic-field-tuned randomness in inhomogeneous altermagnets
Anzumaan R. Chakraborty, Jörg Schmalian, Rafael M. Fernandes
Altermagnetic (AM) states have compensated collinear magnetic configurations that are invariant under a combination of real-space rotation and time reversal. While these symmetries…

Elasto-Hall conductivity and the anomalous Hall effect in altermagnets
Keigo Takahashi, Charles R. W. Steward, Masao Ogata +2
Altermagnets break time-reversal symmetry, preserve the crystal translation invariance, and have a spin density with -wave, -wave, etc. momentum dependencies which do not con…

Topological dipoles of quantum skyrmions
Sopheak Sorn, Jörg Schmalian, Markus Garst
Magnetic skyrmions are spatially localized whirls of spin moments in two dimension, featuring a nontrivial topological charge and a well-defined topological charge density. We demo…
