Locating analytically critical temperatures in some statistical systems.

چکیده
We have found a simple criterion which allows for the straightforward determination of the order-disorder critical temperatures. The method reproduces exactly results known for the two dimensional Ising, Potts and Z(N < 5) models. It also works for the Ising model on the triangular lattice. For systems which are not selfdual our proposition remains an unproven conjecture. It predicts βc = 0.2656... for the two coupled layers of Ising spins. Critical temperature of the three dimensional Ising model is related to the free energy of the two layer Ising system. PACS number: 64.60.Cn hep-lat/9312025 TPJU-23/93 November 1993

Testing a simple criterion for the critical temperature
We investigate the applicability of a simple criterion proposed by Wosiek @Phys. Rev. B 49, 15 023 ~1994!# for locating analytically critical temperatures; we apply it to Ising-like spin models with anisotropic interactions, more than one type of interaction between the spins, and multiple-spin interactions. The predicted critical temperatures only agree with the known exact results or with Mon...

We investigate recently proposed method for locating critical temperatures and introduce some modifications which allow to formulate exact criterion for any self-dual model. We apply the modified method for the Ashkin-Teller model and show that the exact result for a critical temperature is reproduced. We test also a two-layer Ising model for the presence of eventual self-duality.
متن کاملAnalytical approach to the dynamics of facilitated spin models on random networks.
Facilitated spin models were introduced some decades ago to mimic systems characterized by a glass transition. Recent developments have shown that a class of facilitated spin models is also able to reproduce characteristic signatures of the structural relaxation properties of glass-forming liquids. While the equilibrium phase diagram of these models can be calculated analytically, the dynamics ...
متن کاملTheoretical Study on the Kinetics of the Reaction of C2H with C2H2
In this theoretical research, the mechanism of the C2H + C2H2 reaction is studied by high-level quantum-chemical methods and kinetics of the reaction is investigated by statistical rate theories. High-level electronic structure calculation methods including M06-2X, CCSD(T), CBS-Q and G4 methods are employed to explore the doublet potential energy surface of the reaction and compute the molecula...
متن کاملIsing model on two connected Barabasi-Albert networks.
We investigate analytically the behavior of the Ising model on two connected Barabasi-Albert networks. Depending on relative ordering of both networks there are two possible phases corresponding to parallel or antiparallel alignment of spins in both networks. A difference between critical temperatures of both phases disappears in the limit of vanishing inter-network coupling for identical netwo...
