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…
Three-dimensional topological orbital Hall effect caused by magnetic hopfions
Börge Göbel, Samir Lounis
Magnetic hopfions are non-collinear spin textures that are characterized by an integer topological invariant, called Hopf index. The three-dimensional magnetic solitons can be thou…
Nonlinear spin and orbital Rashba-Edelstein effects induced by a femtosecond laser pulse: Simulations for Au(001)
Oliver Busch, Franziska Ziolkowski, Börge Göbel +2
Rashba-type spin-orbit coupling gives rise to distinctive surface and interface phenomena, such as spin-momentum locking and spin splitting. In nonequilibrium settings, one of the…
Chirality-induced selectivity of angular momentum by orbital Edelstein effect in carbon nanotubes
Börge Göbel, Ingrid Mertig, Samir Lounis
Carbon nanotubes (CNTs) are promising materials exhibiting exceptional strength, electrical conductivity, and thermal properties, making them promising for various technologies. Be…
Spontaneous nonreciprocal transport in a gate-tunable ferromagnetic Rashba 2-dimensional electron gas
Gabriel Lazrak, Radu Abrudan, Borge Göbel +10
The broken inversion symmetry at interfaces of complex oxides gives rise to emergent phenomena, including ferromagnetism and Rashba spin-orbit coupling (SOC), which profoundly infl…
Topological orbital Hall effect caused by skyrmions and antiferromagnetic skyrmions
Börge Göbel, Lennart Schimpf, Ingrid Mertig
The topological Hall effect is a hallmark of topologically non-trivial magnetic textures such as magnetic skyrmions. It quantifies the transverse electric current that is generated…
