Fuzzy Dark Matter and Non-Standard Neutrino Interactions
Vedran Brdar, Joachim Kopp, Jia Liu +2
We discuss novel ways in which neutrino oscillation experiments can probe dark matter. In particular, we focus on interactions between neutrinos and ultra-light ("fuzzy") dark matt…
A -algebraic view on the interaction of real- and reciprocal space topology in skyrmion crystals
Pascal Prass, Fabian R. Lux, Emil Prodan +2
Understanding the interaction of real- and reciprocal space topology in skyrmion crystals is an open problem. We approach it from the viewpoint of -algebras and calculate a…
Effective Seiberg-Witten gauge theory of noncollinear magnetism
Fabian R. Lux, Pascal Prass, Stefan Blügel +1
Smoothly varying magnetization textures such as domain walls, skyrmions or hopfions serve as promising candidates for the information bits of the future. Understanding their physic…
Unified topological characterization of electronic states in spin textures from noncommutative K-theory
Fabian R. Lux, Sumit Ghosh, Pascal Prass +2
The nontrivial topology of spin systems such as skyrmions in real space can promote complex electronic states. Here, we provide a general viewpoint at the emergence of topological…
