Exact theory of chirality-dependent p-wave magnetism and Edelstein effect in spin spirals
Börge Göbel, Tom G. Saunderson, Freia Opfermann +3
Spin-momentum locking is widely regarded as a hallmark of relativistic spin-orbit coupling. Here we demonstrate analytically that it can instead emerge solely from magnetic chirali…
Coupled Spin-Orbital -Wave Magnetism via Structural and Magnetic Chirality
Tom G. Saunderson, Börge Göbel, Ersoy ÅaÅıoÄlu +1
Helical spin textures represent the minimal realization of -wave magnetism which is characterized by momentum-odd spin polarization. Independently, structurally chiral crystals…
Chiral-Angle-Controlled Altermagnetic Spin Splitting in Nanotubes
Ersoy Sasioglu, Tom. G. Saunderson, Börge Göbel +2
Altermagnets exhibit momentum-dependent spin splitting despite having zero net magnetization. Here, we show that rolling a two-dimensional (2D) -wave altermagnet into a nanotube…
Higher-order Hall response arises from octupole order and scalar spin chirality in a noncollinear antiferromagnet
Adithya Rajan, Tom G. Saunderson, Fabian R. Lux +19
Noncollinear antiferromagnets can generate a transverse electrical response known as the anomalous Hall effect, even though they possess almost no net magnetization. The microscopi…
Ultra-Stable Weyl Topology Driven by Magnetic Textures in the Shandite Compound Co3Sn2S(2-x)Sex
Dang Khoa Le, Eklavya Thareja, Bektur Konushbaev +5
We employ state-of-the-art first-principles calculations to investigate the shandite compounds Co3Sn2S2, Co3Sn2SeS, and Co3Sn2Se2, which host Weyl fermions and complex magnetic tex…
Giant orbital Zeeman effects in a magnetic topological van der Waals interphase
Tobias Wichmann, Mirco Sastges, Keda Jin +10
Van der Waals (vdW) heterostructures allow the engineering of electronic and magnetic properties by the stacking different two-dimensional vdW materials. For example, orbital hybri…
