Orbital Hall effect and orbital altermagnetism in even- and odd-parity-wave magnetic Lieb lattices
Börge Göbel, Ersoy Şaşıoğlu, Samir Lounis
Altermagnets combine compensated antiferromagnetic order with ferromagnet-like signatures such as spin-polarized bands and, under appropriate conditions, an anomalous Hall response…
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…
Chiral-Angle-Controlled Spin Splitting and Spin Transport in Nanotubes Rolled from d-wave Altermagnets
Ersoy Sasioglu, Tom. G. Saunderson, Börge Göbel +2
Altermagnets combine compensated collinear magnetic order with momentum-dependent spin splitting in the electronic band structure. Here, we show that rolling a two-dimensional (2D)…
-wave Surface Altermagnetism in Centrosymmetric Collinear Antiferromagnets
Ersoy Sasioglu, Ingrid Mertig, Samir Lounis
Broken inversion symmetry at the surfaces of centrosymmetric collinear antiferromagnets lifts combined inversion and time-reversal symmetry () and can, in principle, enable non…
Systematic cRPA study of two-dimensional MAZ materials: From unconventional screening to correlation-driven instabilities
F. Bagherpour, Y. Yekta, H. Hadipour +5
Understanding the interplay between screening, electronic correlations, and collective excitations is essential for the design of two-dimensional quantum materials. Here, we presen…
MIM-Diode-Like Rectification in Lateral 1T/1H/1T-MoS Homojunctions via Interfacial Dipole Engineering
Elias Eckmann, Ersoy Şaşıoğlu, Nicki F. Hinsche +1
Lateral two-dimensional (2D) tunnel diodes that reproduce metal-insulator-metal (MIM)-diode-like rectification without using dissimilar contacts are attractive for scalable nanoele…
