Strong quantum fluctuations dominate the spin-1/2 triangular lattice Heisenberg antiferromagnet, but their survival at spin-1 remains an open question. We address it in K_{2}Ni(SeO_{3})_{2}, a nearly ideal spin-1 realization, using inelastic neutron scattering. Below the ordering temperature T_{N}, coherent one-magnon excitations coexist …

Strong quantum fluctuations and unconventional spin dynamics are well established in the spin-1/2 triangular lattice Heisenberg antiferromagnet. However, their survival in the spin-1 case remains an open question. We investigate the spin dynamics of K$_2$Ni(SeO$_3$)$_2$, a nearly ideal spin-1 triangular lattice Heisenberg …
