Magnetic degeneracy points in interacting two-spin systems: geometrical patterns, topological charge distributions, and their stability
György Frank, Zoltán Scherübl, Szabolcs Csonka +2
Spectral degeneracies of quantum magnets are often described as diabolical points or magnetic Weyl points, which carry topological charge. Here, we study a simple, yet experimental…

Observation of spin-orbit coupling induced Weyl points and topologically protected Kondo effect in a two-electron double quantum dot
Zoltán Scherübl, András Pályi, György Frank +8
Recent years have brought an explosion of activities in the research of topological aspects of condensed-matter systems. Topologically non-trivial phases of matter are typically ac…
