Magnon-induced long-range correlations and their neutron-scattering signature in quantum magnets

ORAL

Abstract

In the ordered phases of classical ferromagnets (FMs) and antiferromagnets (AFMs), the long-range correlations induced by the magnons lead to a singular wavenumber dependence of the longitudinal order-parameter susceptibility: $\chi_L\sim 1/k^{4-d}$ for $2
