A $C^\ast$-algebraic view on the interaction of real- and reciprocal space topology in skyrmion crystals Open
Understanding the interaction of real- and reciprocal space topology in skyrmion crystals is an open problem. We approach it from the viewpoint of C^\ast -algebras and calculate all admissible Chern numbers of a strongly coupled tight-…

Unified topological characterization of electronic states in spin textures from noncommutative -theory Open
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 spectral gaps in spin systems based on the methods of nonco…

Effective Seiberg-Witten gauge theory of noncollinear magnetism Open
Smoothly varying magnetization textures such as domain walls, skyrmions or hopfions serve as promising candidates for the information bits of the future. Understanding their physical properties is both a major field of interest and a theor…

Fuzzy dark matter and nonstandard neutrino interactions Open
We discuss novel ways in which neutrino oscillation experiments can probe\ndark matter. In particular, we focus on interactions between neutrinos and\nultra-light ("fuzzy") dark matter particles with masses of order $10^{-22}$ eV.\nIt has …
