Abstract

Motivated by the recent quasi-elastic neutron scattering experiment, we extend the spin-dynamics simulation on the triangular-lattice Heisenberg antiferromagnet, to observe a sharp central peak of its energy width $\sim 0.001J$ ( $J$ the exchange coupling) of the $Z_2$ -vortex origin, consistently with the experiment.
