Topological hydrodynamics in spin-triplet superconductors
Chau Dao, Eric Kleinherbers, Bjørnulf Brekke +1
Due to the structure of the underlying SO(3) -vector order parameter, spin triplet superconductors exhibit a bulk-edge correspondence linking the circulation of supercur…
Coexistence of -wave magnetism and superconductivity
Pavlo Sukhachov, Hans Gløckner Giil, Bjørnulf Brekke +1
The symmetry requirements for realizing unconventional compensated magnets with spin-polarized bands such as altermagnets have recently been uncovered. The most recent addition to…
Shear Strain-Induced Multiferroic Response in the Altermagnetic Semiconductor CuFeS
Roman Malyshev, Bjørnulf Brekke, Ingeborg-Helene Svenum +4
CuFeS is an altermagnetic semiconductor that is lattice-matched with silicon and has a high Néel temperature. It is nonpolar and magnetically compensated in its structural gro…
Minimal Models and Transport Properties of Unconventional -Wave Magnets
Bjørnulf Brekke, Pavlo Sukhachov, Hans Gløckner Giil +2
New unconventional compensated magnets with a -wave spin polarization protected by a composite time-reversal translation symmetry have been proposed in the wake of altermagnets.…
