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…
Multiband strong-coupling superconductors with spontaneously broken time-reversal symmetry
Niels Henrik Aase, Kristian Mæland, Asle Sudbø
We study superconducting three-band systems within strong-coupling Eliashberg theory. In particular, we search for phase-frustrated superconducting systems with spontaneous time-re…
Topological superconductivity mediated by magnons of helical magnetic states
Kristian Mæland, Sara Abnar, Jacob Benestad +1
We recently showed that spin fluctuations of noncoplanar magnetic states can induce topological superconductivity in an adjacent normal metal [Mæland et al., Phys. Rev. Lett. 130,…
Stability of superconducting gap symmetries arising from antiferromagnetic magnons
Chi Sun, Kristian Mæland, Asle Sudbø
We consider a planar heterostructure consisting of a normal metal in proximity to an antiferromagnetic insulator, with an interlayer exchange coupling between the metal and the ins…
Topological Superconductivity Mediated by Skyrmionic Magnons
Kristian Mæland, Asle Sudbø
Topological superconductors are associated with the appearance of Majorana bound states, with promising applications in topologically protected quantum computing. In this Letter, w…
Quantum topological phase transitions in skyrmion crystals
Kristian Mæland, Asle Sudbø
Topological order is important in many aspects of condensed matter physics, and has been extended to bosonic systems. In this Letter we report on the nontrivial topology of the mag…
Quantum fluctuations in the order parameter of quantum skyrmion crystals
Kristian Mæland, Asle Sudbø
Traditionally, skyrmions are treated as continuum magnetic textures of classical spins with a well-defined topological skyrmion number. Owing to their topological protection, skyrm…
