Correlation Inequalities of Gks Type for the Potts Model

چکیده

Correlation inequalities are presented for functionals of a ferromagnetic Potts model with external field, using the random-cluster representation. These results extend earlier inequalities of Ganikhodjaev–Razak and Schonmann, and yield also GKS-type inequalities when the spin-space is taken as the set of qth roots of unity.

J an 2 00 8 correlation inequalities for spin glass in one dimension

We prove two inequalities for the direct and truncated correlation for the nearestneighboor one-dimensional Edwards-Anderson model with symmetric quenched disorder. The second inequality has the opposite sign of the GKS inequality of type II. In the non symmetric case with positive average we show that while the direct correlation keeps its sign the truncated one changes sign when crossing a su...

Correlation Inequalities for Quantum Spin Systems with Quenched Centered Disorder

Quantum spin system with quenched randomness are both important and theoretically challenging. They are widely used as models for metallic alloys in condensed matter physics, see [2] for a review. They are also important in combinatorial optimization problems especially in relation to quantum annealing procedures [3] and quantum error correcting codes [4]. One approach to studying such macrosco...

Correlation Inequalities for Generalized Potts Model: General Griffiths’ Inequalities

In this paper, correlation inequalities which have been considered on Ising model are extended to q-Potts model. It is considered on generalized Potts model with interaction of any number of spins. We replace the set of spin values F = {1, 2, · · · , q} by the centered set F = {−(q−1)/2,−(q−3)/2, · · · , (q−3)/2, (q−1)/2}. Let N be the subset of one-dimensional lattice with n vertices, γ = (σ1,...

Two Griffiths inequalities for the Potts model

Ganikhodjaev and Razak have proved versions of the two Griffiths inequalities for the ferromagnetic Potts model. We show how their inequalities may be derived via the FKG inequality for the random-cluster representation of the Potts model.

Phase Transitions with Four-Spin Interactions

Using an extended Lee-Yang theorem and GKS correlation inequalities, we prove, for a class of ferromagnetic multi-spin interactions, that they will have a phase transition (and spontaneous magnetization) if, and only if, the external field h = 0 (and the temperature is low enough). We also show the absence of phase transitions for some nonferromagnetic interactions. The FKG inequalities are sho...
