Abstract: (APS)
The Berlin-Kac spherical model (or"spherical approximation to the Ising model") HSM=−JΣ〈ij〉μiμj, with Σj=1Nuj2=N, is found to be equivalent to the ν→∞ limit of the Hamiltonian H(ν)=−JΣ〈ij〉Si(ν)·Sj(ν), where Si(ν) are isotropically interacting ν-dimensional classical spins.References(6)
