چکیده
The first-order phase transition in the one-dimensional q-state Potts model with long-range interactions decaying with distance as 1/r 1+σ has been studied by Monte Carlo numerical simulations for 0 < σ ≤ 1 and integer values of q > 2. On the basis of finite-size scaling analysis of interface free energy ∆F L , specific heat and Binder's fourth order cumulant, we obtain the first-order transition which occurs for σ below a threshold value σ c (q).

The critical behaviour of the one-dimensional q-state Potts model with long-range interactions decaying with distance r as r −(1+σ) has been studied in the wide range of parameters 0 < σ ≤ 1 and 1 16 ≤ q ≤ 64. A transfer matrix has been constructed for a truncated range of interactions for integer and continuous q, and finite range scaling has been applied. Results for the phase diagram and the...

Generalizing the mapping between the Potts model with nearest neighbour interaction and the six vertex model, we build a family of " fused Potts models " related to the spin k/2 Uqsu(2) invariant vertex model and quantum spin chain. These Potts models have still variables taking values 1,. .. , Q (√ Q = q + q −1) but they have a set of complicated multi spin interactions. The general technique ...

The two-dimensional Potts Model with seven states under external field is studied using a cluster algorithm. Cluster size distribution and the fluctuations in the average cluster size provide helpful information on the order of phase transitions. Potts model [1] is known to have a very rich critical behaviour and considered as a testing ground for both analytical and numerical methods. Recently...

The first-order phase transition in the three-state Potts model with long-range interactions decaying as 1/r has been examined by numerical simulations using the recently proposed Luijten-Blöte algorithm. By applying scaling arguments to the interface free energy, the Binder’s fourth-order cumulant, and the specific heat maximum, the change in the character of the transition through variation o...
