Breakdown of magnons in a strongly spin-orbital coupled magnet
Breakdown of magnons in a strongly spin-orbital coupled magnet
The description of quantized collective excitations stands as a landmark in the quantum theory of condensed matter. A prominent example occurs in conventional magnets, which support bosonic magnons-quantized harmonic fluctuations of the ordered spins. In striking contrast is the recent discovery that strongly spin-orbital-coupled magnets, such as α-RuCl3, may display …
