Thermal spin dynamics of Kitaev magnets $-$ scattering continua and magnetic field induced phases within a stochastic semiclassical approach

Oliver Franke, Dumitru Călugăru, Andreas Nunnenkamp +1

The honeycomb magnet $\alpha -$RuCl${}_3$ is a prime candidate material for realizing the Kitaev quantum spin liquid (QSL), but it shows long-range magnetic order at low temperature. Never…
