WebFigure 1. Loop representation of the random cluster Ising model. Weight of the configuration is proportional to (√ q)# loops, with q = 2. The sites of the original Ising lattice are colored in black, while the sites of the dual lattice are colored in white. Loops separate clusters from dual clusters, which are also pictured, the former in bold. WebApr 12, 2024 · We report the Griffiths phase (GP)-like state along with a cluster-glass-like state in geometrically frustrated antiferromagnetic Cr-substituted ${\text{Y}}_{2}{\text{Ir}}_{2}{\text{O}}_{7}$ pyrochlore iridates. The strength of the GP-like behavior increases with substitution. Interestingly, isothermal remanent magnetization …
WebOct 11, 2016 · This article studies the planar Potts model and its random-cluster representation. We show that the phase transition of the nearest-neighbor ferromagnetic q-state Potts model on $${\\mathbb{Z}^2}$$ Z 2 is continuous for $${q \\in \\{2,3,4\\}}$$ q ∈ { 2 , 3 , 4 } , in the sense that there exists a unique Gibbs state, or equivalently that there is … WebIsing models and Metropolis algorithm. #. Ising models are a class of simple lattice based spin s = ± 1 ssytems which are widely used for studying the nature of phase transitions. Many aspects of phase transitions are universal and independent of mciroscopic details of interactions. Hence One wants as simple of a model capable of displaying ...

Atomic Scale Simulation . 3 Mapping a liquid-gas model to the Ising Model • For liquid-gas transition let n(r) be the density at lattice site WebThere is a generalisation of the Ising model to q ≥2 spins, known as the q-state Potts model, of which the Ising model is the special case q =2. Although the even subgraphs and spin formulations are defined only for integer q, the random cluster model makes sense for arbitrary positive real q. Thus, by studying the dynamics of the random ...
