Chiral spin-textures in van der Waals heterostructures
Nihad Abuawwad, Samir Lounis
Chiral spin textures such as skyrmions have attracted considerable attention due to their nontrivial topology, chirality, stability at the nanoscale, and potential for low-power sp…
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…
Oxygen-driven altermagnetic symmetry inducing d-wave superconductivity in the cuprates and nickelates
Tom G. Saunderson, James F. Annett, Samir Lounis
Since the discovery of cuprate high-Tc superconductivity, numerous theoretical frameworks have been proposed to explain its mechanism; Anderson's RVB picture [Science 235, 1196-119…
Influence of Interlayer Stacking on Optical Behavior in WSe/MoS van der Waals Heterostructures
Widad Louafi, Karim Rezouali, Daniele Varsano +3
We investigate the impact of crystal alignment on excitonic behavior in WSe/MoS van der Waals heterostructures by comparing eclipsed (AA) and staggered (AB) stacking co…
Frustrated magnetism in Mn films on Ag(111) surface: from chiral in-plane Néel state to row-wise antiferromagnetism
Selcuk Sözeri, Nihad Abuawwad, Amal Aldarawsheh +1
We conduct a comprehensive density functional theory (DFT) study to explore the intricate magnetic properties of frustrated Mn monolayer on the Ag(111) surface. Spin-polarized scan…
