- 要約等By using the Monte Carlo si......we investigate the critical behavior of the 1-dimensional spin system with infinite long-range (LR) interaction r^{-(1+σ)}. By changing the value σ, we compare the results with those of the d-dimensional spin system with the nearest-neighbor(NN) interaction only. In the case of XY spin model, we obta......nsitions, i.e. the mean field typ......0 < σ < 0.5 , the σ-dependent no......at σ = 1 as in the NN model of d > 4 , 2 < d ......spectively. In the case of q-state clock spin model with σ = 1, we also confirm the BKT-like transition together with the similar q-dependence of the critical behavior to that...
