The fate of odd-parity magnetism in one dimension
Kasper Rettedal Eikeland, Sondre Duna Lundemo, Asle Sudbø
We consider a one-dimensional model for a -wave magnet within the bosonization framework. The model consists of itinerant electrons described by an extended Hubbard model couple…
Divergent spin conductivity on the verge of ferromagnetic quantum criticality
Sondre Duna Lundemo, Asle Sudbø
We show that the spin conductivity of a metal approaching a ferromagnetic quantum critical point exhibits divergent fluctuation corrections. This effect arises from critical spin f…
Fluctuation conductivity in ultraclean multicomponent superconductors
Sondre Duna Lundemo, Asle Sudbø
We consider the intrinsic fluctuation conductivity in metals with multiply sheeted Fermi surfaces approaching a superconducting critical point. Restricting our attention to extreme…
Quantum critical scaling of altermagnetism
Sondre Duna Lundemo, Flavio S. Nogueira, Asle Sudbø
The term altermagnetism has recently been introduced to describe the Néel order of a class of materials whose magnetic sublattices are neither related by translation nor inversion.…
Topology-driven deconfined quantum criticality in magnetic bilayers
Sondre Duna Lundemo, Flavio S. Nogueira, Asle Sudbø
Two-dimensional quantum antiferromagnets are believed to host phases of matter whose excitations are more fundamental than those of the ordered phases. When combining two such spin…
Topological superconductivity induced by a Kitaev spin liquid
Sondre Duna Lundemo, Asle Sudbø
We study the effective low-energy fermionic theory of the Kondo-Kitaev model to leading order in the Kondo coupling. Our main goal is to understand the nature of the superconductin…
