Correction to the leading singularity of the order parameter of the four-dimensional Ising ferromagnet [4]

Publikation: Bidrag til tidsskriftTidsskriftartikel

The Monte Carlo technique is used to calculate the order parameter, Phi , of the four-dimensional spin-1/2 Ising ferromagnet in a simple hypercubic lattice. The order-parameter data are described by Phi (t)=B(-t)1/2 mod ln(-t) mod 1/3(1+Q ln mod ln(-t) mod / mod ln(-t) mod ) in the range 0.01<or approximately=-t identical to (T c-T)/Tc<0.56 with parameters B=1.543+or-0.002 and Q=-0.030+or-0.02. The form of Phi (t) agrees with that predicted by renormalisation group theory.
