Fig. 1: Inelastic neutron scattering (INS) spectra measured at zero field.
From: Field control of quasiparticle decay in a quantum antiferromagnet
a False color map of INS spectra acquired at HRC. White circles represent peak energy obtained from fitting results of constant q cuts. Dotted, solid, and dashed curves are dispersion relations calculated using linear extended spin wave theory using best-fit parameters. b, c High-symmetry points in reciprocal space.
