Geometrical torque on magnetic moments coupled to a correlated antiferromagnet
Nicolas Lenzing, David Krüger, Michael Potthoff
The geometrical spin torque mediates an indirect interaction of magnetic moments, which are weakly exchange coupled to a system of itinerant electrons. It originates from a finite…

Emergent Non-Abelian Gauge Theory in Coupled Spin-Electron Dynamics
Nicolas Lenzing, Alexander I. Lichtenstein, Michael Potthoff
A clear separation of the time scales governing the dynamics of "slow" and "fast" degrees of freedom often serves as a prerequisite for the emergence of an independent low-energy t…

Microscopic theory of spin friction and dissipative spin dynamics
Nicolas Lenzing, David Krüger, Michael Potthoff
The real-time dynamics of local magnetic moments exchange coupled to a metallic system of conduction electrons is subject to dissipative friction even in the absence of spin-orbit…
