Functionalization of -wave altermagnets: spin-splitter effect enabled by surfaces
Sopheak Sorn
We investigate surfaces of a -wave altermagnet(AM) and show that they provide a platform for realizing -wave altermagnetism and the associated spin-splitter functionality. Us…
Projected altermagnetism by symmetry reduction at surfaces and in thin films
Sopheak Sorn, Charanpreet Singh, Lukasz Plucinski +3
Altermagnets are a newly identified class of magnetic materials that combine vanishing net magnetization within the unit cell with spin-split electronic states. Their theoretical d…
The 2026 Skyrmionics Roadmap
Sabri Koraltan, Claas Abert, Manfred Albrecht +64
Magnetic skyrmions and related topological spin textures have emerged as a central topic in condensed-matter physics, combining fundamental significance with potential for transfor…
Activation of anomalous Hall effect and orbital magnetization by domain walls in altermagnets
Sopheak Sorn, Yuriy Mokrousov
Altermagnets are an emerging class of unconventional antiferromagnets, characterized by a Néel ordering that does not break the translation symmetry of the underlying lattice. Dep…
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…
Antichiral surface states and Su-Schrieffer-Heeger physics in rutile altermagnets
Sopheak Sorn
We study surface states and domain wall bound states in altermagnets using a rutile-lattice tight-binding model of electrons coupled to a Néel order. We discover that two symmetry…
