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…
