Spin-orbit coupling by design in quantum state engineering of atomically defined quantum dots
Hermann Osterhage, Julian H. Strik, Ivan Ado +4
Tuning spin-orbit coupling is essential in controlling both spin and charge in confined semiconductor nanostructures, yet it is rarely a truly controllable parameter. Here, we show…
Magnetic moment of electrons in systems with spin-orbit coupling
I. A. Ado, M. Titov, Rembert A. Duine +1
Magnetic effects originating from spin-orbit coupling (SOC) have been attracting major attention. However, SOC contributions to the electron magnetic moment operator are convention…
Orbital Edelstein effect from the gradient of a scalar potential
I. A. Ado, M. Titov, Rembert A. Duine +1
We study the orbital Edelstein effect (OEE) that originates from a particular inversion symmetry breaking mechanism: an asymmetric scalar potential. We compute OEE of this kind wit…
Orbital magnetization from interface reflections in a conductor with charge current
J. Voss, I. A. Ado, M. Titov
We propose that a high-quality flat interface or boundary can serve as a long-range skew scatterer for charged quasiparticles in a metal. When an electric current flows parallel to…
Position operators and interband matrix elements of scalar and vector potentials in the 8-band Kane model
I. A. Ado, M. Titov, Rembert A. Duine +1
We diagonalize the 8-band Kane Hamiltonian with a proper inclusion of the interband matrix elements of the scalar and vector potentials. This leads, among other results, to a modif…
Kubo formula for dc conductivity: generalization to systems with spin-orbit coupling
I. A. Ado, M. Titov, Rembert A. Duine +1
We revise the Kubo formula for the electric dc conductivity in the presence of spin-orbit coupling (SOC). We discover that each velocity operator that enters this formula differs f…
Quartic asymmetric exchange for two-dimensional ferromagnets with trigonal prismatic symmetry
I. A. Ado, Gulnaz Rakhmanova, Dmitry A. Zezyulin +2
We suggest a possible origin of noncollinear magnetic textures in ferromagnets (FMs) with the point group symmetry. The suggested mechanism is different from the Dzyaloshi…
Anisotropy of spin-transfer torques and Gilbert damping induced by Rashba coupling
I. A. Ado, P. M. Ostrovsky, M. Titov
Spin-transfer torques (STT), Gilbert damping (GD), and effective spin renormalization (ESR) are investigated microscopically in a 2D Rashba ferromagnet with spin-independent Gaussi…
Chiral ferromagnetism beyond Lifshitz invariants
I. A. Ado, A. Qaiumzadeh, A. Brataas +1
We consider a contribution to the micromagnetic energy density that is linear with respect to the first spatial derivatives of the local magnetization direction. Fo…
Spin-torque resonance due to diffusive dynamics at a surface of topological insulator
R. J. Sokolewicz, I. A. Ado, M. I. Katsnelson +2
We investigate spin-orbit torques on magnetization in an insulating ferromagnetic (FM) layer that is brought into a close proximity to a topological insulator (TI). In addition to…
Asymmetric and symmetric exchange in a generalized 2D Rashba ferromagnet
I. A. Ado, A. Qaiumzadeh, R. A. Duine +2
Dzyaloshinskii-Moriya interaction (DMI) is investigated in a 2D ferromagnet (FM) with spin-orbit interaction of Rashba type at finite temperatures. The FM is described in the conti…
Theory of the Interfacial Dzyaloshinskii-Moriya Interaction in Rashba Antiferromagnets
Alireza Qaiumzadeh, Ivan A. Ado, Rembert A. Duine +2
In antiferromagnetic (AFM) thin films, broken inversion symmetry or coupling to adjacent heavy metals can induce Dzyaloshinskii-Moriya (DM) interactions. Knowledge of the DM parame…
Microscopic theory of spin-orbit torques and skyrmion dynamics
I. A. Ado, O. A. Tretiakov, M. Titov
We formulate a general microscopic approach to spin-orbit torques in thin ferromagnet/heavy-metal bilayers in linear response to electric current or electric field. The microscopic…
