Orbital current rectifier and linear magnon Edelstein effect in -wave antialtermagnets

Kristian Mæland, Björn Trauzettel

We show that -wave magnets efficiently generate magnetization via a linear thermal Edelstein effect arising from the orbital magnetic moments of their magnons. Furthermore, they…

Mechanism for Nodal Topological Superconductivity on PtBi Surface

Kristian Mæland, Giorgio Sangiovanni, Björn Trauzettel

Experiments show that the Weyl semimetal PtBi hosts unconventional superconductivity in its topological surface states. Hence, the material is a candidate for intrinsic topolog…

Strong-coupling approach to temperature dependence of competing orders of superconductivity: Possible time-reversal symmetry breaking and nontrivial topology

Chi Sun, Kristian Mæland, Even Thingstad +1

We use strong-coupling Eliashberg theory to study the competition of separate superconducting orders at low temperatures. Specifically, we study magnon-mediated superconductivity i…

Many-body effects on superconductivity mediated by double-magnon processes in altermagnets

Kristian Mæland, Bjørnulf Brekke, Asle Sudbø

Altermagnets exhibit a large electron spin splitting which can be understood as a result of strong coupling between itinerant electrons and localized spins. We consider superconduc…

Exceeding the Chandrasekhar-Clogston limit in flat-band superconductors: A multiband strong-coupling approach

Kristian Mæland, Asle Sudbø

Hybrid systems of superconductors and magnets display several intriguing properties, both from a fundamental physics point of view and with practical applications. Promising applic…
