Block spin techniques applied to the ising model

摘要: A detailed study of the critical behaviour Ising model in 1+1 and 2+1 dimensions is made using an approximate real space renormalization transformation which involves block spins. The indices α, β, η, ν are calculated compared with previous results, as couplingyc. method shown to respect one scaling relations, 1+1D some exact results reproduced (yc=1, ν=1).
