Magnon-induced nonanalyticities in thermodynamic and transport properties of quantum ferromagnets

ORAL

Abstract

Soft modes and their effects on thermodynamic and transport properties are of great interest. An example of a nonanalyticity induced by Goldstone modes is the divergence of the longitudinal susceptibility, $\chi _{\mathrm{L}}(k) \sim 1/k^{4-d}$, in a classical isotropic Heisenberg ferromagnet in $2
