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…

Spin fluctuations after quantum quenches in the S=1 Haldane chain: numerical validation of the semi-semiclassical theory
Miklós Antal Werner, Cătălin Paşcu Moca, Örs Legeza +2
We study quantum quenches in the Heisenberg spin chain and show that the dynamics can be described by the recently developed semi-semiclassical method based on particles prop…
