MICROCANONICAL DETERMINATION OF THE ORDER PARAMETER CRITICAL EXPONENT

Alfred Hüller, Michel Pleimling

A highly efficient Monte Carlo method for the calculation of the density of states of classical spin systems is presented. As an application, we investigate the density of states ΩN(E, M) of two- and three-dimensional Ising models with N spins as a function of energy E and magnetization M. For a fixed energy lower than a critical value Ec,N the density of states exhibits two sharp maxima at M = ± Msp(E) which define the microcanonical spontaneous magnetization. An analysis of the form Msp(E) ∝ (Ec, ∞ - E)βε yields very good results for the critical exponent βε, thus demonstrating that critical exponents can be determined by analyzing directly the density of states of finite systems.

DYNAMICAL CRITICAL BEHAVIOUR OF HEISENBERG FERROMAGNETS FOR T ≥ Tc

Harald Iro

From an O(ε)-calculation (ε = 6 - d) of the dynamical spin correlation function in a Heisenberg system for T ≥ Tc an expression for that function applicable in dimension d = 3 is deduced. It comprises the expected limiting behaviour in different sectors of the critical region.
