Beyond spin-1/2: Multipolar spin-orbit coupling in noncentrosymmetric crystals with time-reversal symmetry
Masoud Bahari, Kristian Mæland, Carsten Timm +1
We develop a symmetry-adapted multipolar theory close to the bulk point for time-reversal-symmetric, noncentrosymmetric crystals in the str…
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…
Spin-resolved quasiparticle interference patterns on altermagnets via non-spin-resolved scanning tunneling microscopy
Eric Petermann, Kristian Mæland, Björn Trauzettel
We investigate quasiparticle interference on an altermagnetic Lieb-like lattice and show how a non-spin-polarized scanning tunneling microscopy measurement can yield effectively sp…
Phonon-mediated intrinsic topological superconductivity in Fermi arcs
Kristian Mæland, Masoud Bahari, Björn Trauzettel
We propose that phonons can intrinsically mediate topological superconductivity on the surface of Weyl semimetals. Weyl semimetals are gapless topological materials with nondegener…
Master's Thesis: Excitation Spectrum of a Weakly Interacting Spin-Orbit Coupled Bose-Einstein Condensate
Kristian Mæland
A weakly interacting, spin-orbit coupled, two-component, ultracold Bose gas bound to a Bravais lattice is studied. Motivated by recent experimental advances in the field of synthet…
