The Glassy Potts Model
We introduce a Potts model with quenched, frustrated disorder, that enjoys of a gauge symmetry that forbids spontaneous magnetization, and allows the glassy phase to extend from Tc down to T = 0. We study numerical the 4 dimensional model with q = 4 states. We show the existence of a glassy phase, and we characterize it by studying the probability distributions of an order parameter, the binder...
متن کاملMulticanonical Potts Model Simulation
Relying on the recently proposed multicanonical algorithm, we present a numerical simulation of the first order phase transition in the 2d 10-state Potts model on lattices up to sizes 100 × 100. It is demonstrated that the new algorithm lacks an exponentially fast increase of the tunneling time between metastable states as a function of the linear size L of the system. Instead, the tunneling ti...
متن کاملTwo 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.
متن کاملDynamic Exponents for Potts Model Cluster Algorithms
We have studied the Swendsen-Wang and Wolff cluster update algorithms for the Ising model in 2, 3 and 4 dimensions. The data indicate simple relations between the specific heat and the Wolff autocorrelations, and between the magnetization and the Swendsen-Wang autocorrelations. This implies that the dynamic critical exponents are related to the static exponents of the Ising model. We also inves...
متن کاملA Bayesian hierarchical model for detecting haplotype-haplotype and haplotype-environment interactions in genetic association studies.
OBJECTIVE Genetic association studies based on haplotypes are powerful in the discovery and characterization of the genetic basis of complex human diseases. However, statistical methods for detecting haplotype-haplotype and haplotype-environment interactions have not yet been fully developed owing to the difficulties encountered: large numbers of potential haplotypes and unknown haplotype pairs...
