Multicritical Points of Potts Spin Glasses on the Triangular Lattice
We predict the locations of several multicritical points of the Potts spin glass model on the triangular lattice. In particular, continuous multicritical lines, which consist of multicritical points, are obtained for two types of two-state Potts (i.e., Ising) spin glasses with twoand three-body interactions on the triangular lattice. These results provide us with numerous examples to further ve...
متن کاملFerromagnetic Potts Model: Refined #BIS-hardness and Related Results
Recent results establish for the hard-core model (and more generally for 2-spin antifer-romagnetic systems) that the computational complexity of approximating the partition func-tion on graphs of maximum degree ∆ undergoes a phase transition that coincides with theuniqueness/non-uniqueness phase transition on the infinite ∆-regular tree. For the ferromag-netic Potts model we...
متن کاملZero-Temperature Dynamics of ± J Spin Glasses and Related Models
We study zero-temperature, stochastic Ising models σ on Z with (disordered) nearest-neighbor couplings independently chosen from a distribution μ on R and an initial spin configuration chosen uniformly at random. Given d, call μ type I (resp., type F) if, for every x in Z, σ x flips infinitely (resp., only finitely) many times as t → ∞ (with probability one) — or else mixed type M. Models of ty...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولIsing and Potts models
At the critical point in two dimensions, the number of percolation clusters of enclosed area greater than A is proportional to A−1, with a proportionality constant C that is universal. We show theoretically (based upon Coulomb gas methods), and verify numerically to high precision, that C = 1/8 √ 3π = 0.022972037 . . .. We also derive, and verify to varying precision, the corresponding constant...
