Ising critical exponents

WitrynaThe critical exponent q * depends on the structure of the operator, presence of strong lower-order terms, geometry of the domain G. In [33] Kalton and Verbitsky gave necessary and sufficient conditions for existence of positive solutions to L u = Wu q + f, u = 0 on ∂ G, for smooth domains G and q >1, in terms of the Green's function Γ G of L … WitrynaA multispin coding program for site-diluted Ising models on large simple cubic lattices is described in detail. The spontaneous magnetization is computed as a function of temperature, and the critical temperature as a function of concentration is found to agree well with the data of Marro et al. and Landau for smaller systems.
