Critical behavior of noninteracting spin waves

  • Lincoln Stoller
Article

Abstract

Monte Carlo techniques are used to show that a free-spin-wave theory of the quantum Heisenberg spin-1/2 ferromagnet, formulated to accurately represent the state space of the underlying system, predicts the critical temperature of the interacting theory to within 1% and critical exponents to within a factor of two.
