A Few Layered n-Vector Model in the Limit n ->
S. Hikami, Ren Abe · Progress of Theoretical Physics · 1976
The hypercubical n-vector model with finite thickness is investigated in the limit n → ∞. Numerical calculations of critical temperatures are performed for systems with a few layers where each layer is three-dimensional. It is shown that for the free and boundary condition the n-vector model in the limit n → ∞ is not necessarily equivalent to the corresponding spherical model.
