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…
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.…
Quasiclassical theory of superconducting spin-splitter effects and spin-filtering via altermagnets
Hans Gløckner Giil, Bjørnulf Brekke, Jacob Linder +1
Conducting altermagnets have recently emerged as intriguing materials supporting strongly spin-polarized currents without magnetic stray fields. We demonstrate that altermagnets en…
Quantum Theory of Spin-Transfer and Spin-Pumping in Collinear Antiferromagnets and Ferrimagnets
Hans Gløckner Giil, Arne Brataas
Antiferromagnets are promising candidates as active components in spintronic applications. They share features with ferrimagnets in that opposing spin orientations exist in two or…
Effective quasiclassical models for odd-frequency superconductivity: energy-symmetry, preserved spectral weight, and Meissner response
Hans Gløckner Giil, Jacob Linder
The odd-frequency superconducting state appears generally in hybrid structures consisting of conventional superconductors and other materials, and features electrons that form temp…
