Spin-dependent quasiparticle lifetimes in altermagnets
Kristoffer Leraand, Kristian Mæland, Asle Sudbø
We investigate many-body effects on the spin-split electron bands in altermagnets by computing the electron self-energy arising from interactions with magnons, phonons, and hybridi…
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…
Quantum critical scaling of altermagnetism
Sondre Duna Lundemo, Flavio S. Nogueira, Asle Sudbø
The term altermagnetism has recently been introduced to describe the Néel order of a class of materials whose magnetic sublattices are neither related by translation nor inversion.…
