Wavevector dependence of fluctuations in the cluster approximation

S. Havlin

Research output: Contribution to journalArticlepeer-review


The self-consistent cluster approximation for the Ising model is extended to obtain the wavevector dependence of the fluctuations. When the method is applied to the one-dimensional Ising model the result for the wavevector-dependent susceptibility is the exact result.
