Curvature-induced bound states in quantum wires
Tim Bergmann, Benjamin Schwager, Jamal Berakdar
A classical particle under spatial constraints is strictly confined to live on a specific space manifold or path, but this assumption is incompatible with the zero-point fluctuatio…
Signatures of real-space geometry, topology, and metric tensor in quantum transport in periodically corrugated spaces
Benjamin Schwager, Theresa Appel, Jamal Berakdar
The motion of a quantum particle constrained to a two-dimensional non-compact Riemannian manifold with non-trivial metric can be described by a flat-space Schroedinger-type equatio…
Anisotropic light-tailored RKKY interaction in two-dimensional -wave altermagnets
Mohsen Yarmohammadi, Ulrich Zülicke, Jamal Berakdar +2
Altermagnets are known in spintronics for their intrinsic spin-splitting and unconventional magnetic responses, particularly to magnetic impurities. However, effectively controllin…
Magneto-optical polarisation texturing
Koray Koksal, Fatma Tambag, Jamal Berakdar +1
Left and right circularly polarized transverse electromagnetic waves propagate at slightly different speeds in a magnetic material leading to a polarization rotation by an amount p…
Probing topological phases in a perturbed Kane-Mele model via RKKY interaction: Application to monolayer jacutingaite PtHgSe
Mohsen Yarmohammadi, Saeed Rahmanian Koshkaki, Jamal Berakdar +2
Quantum spin Hall insulators (QSHIs) are promising for spintronics, leveraging strong spin-orbit coupling for efficient spin manipulation via electrical and optical methods, with p…
