Unconventional criticality in -invariant loop-constrained Landau theory
Svitlana Kondovych, Asle Sudbø, Flavio S. Nogueira
We study an unconventional phase transition in ferroelectrics where the polarization field is constrained to be divergence-free, allowing only loop-like configurations. This local…
Exchange tensors, generalized RKKY interactions, and magnetization dynamics in heterostructures of ferromagnets and topological insulators
Christian Svingen Johnsen, Asle Sudbø
We present a comprehensive theoretical analysis of magnetic heterostructures composed of ferromagnetic (FM) layers interfaced with three-dimensional topological insulators (TIs). I…
Skyrmion Lattice Order Controlled by Confinement Geometry
Raphael Gruber, Jan Rothörl, Simon M. Fröhlich +8
Magnetic skyrmions forming two-dimensional (2D) lattices provide a versatile platform for investigating phase transitions predicted by Kosterlitz-Thouless-Halperin-Nelson-Young (KT…
Skyrmion Lattice Domain Formation in a Non-Flat Energy Landscape
Raphael Gruber, Jan Rothörl, Simon M. Fröhlich +9
Magnetic skyrmions are chiral spin structures with non-trivial topology that comprise two-dimensional quasi-particles and are promising information carriers for data storage and pr…
Orbital splitter effect and spatial resolution of current-induced orbital accumulation
Niels Henrik Aase, Erik Wegner Hodt, Karl Bergson Hallberg +2
The emergence of an orbital angular momentum (OAM) response to a charge current holds promise for technological applications, allowing electrical control of magnetization dynamics.…
Dynamically generated spin-interactions and nutational spin inertia in normal metal-ferromagnet heterostructures
Christian Svingen Johnsen, Asle Sudbø
We consider the spin dynamics of a normal metal-ferromagnet heterostructure, with emphasis on spin-nutation terms arising from a dynamical Ruderman-Kittel-Kasuya-Yosida (RKKY) inte…
