Notes on correlation inequalities and the existence of Gibbs measures for the Ising model
In particular, if δ ∈ Ωx is the configuration defined by δ y = δxy, then the event δ occurs if the spin at x is positive. Given disjoint Λ1 and Λ2 we denote the concatenation of configurations ωΛi ∈ ΩΛi for i = 1, 2 by ωΛ1ωΛ2 ∈ ΩΛ1∪Λ2 . We also define the projection maps σx : ω 7→ ωx. These will become random variables once Ω is equipped with a measure. Definition 1. The Hamiltonian H β,h : ΩΛ ...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
the effect of using model essays on the develpment of writing proficiency of iranina pre-intermediate efl learners
abstract the present study was conducted to investigate the effect of using model essays on the development of writing proficiency of iranian pre-intermediate efl learners. to fulfill the purpose of the study, 55 pre- intermediate learners of parsa language institute were chosen by means of administering proficiency test. based on the results of the pretest, two matched groups, one as the expe...
On complexity of the quantum Ising model
We study the computational complexity of estimating the ground state energy and simulating the adiabatic evolution for the transverse field Ising model (TIM). It is shown that the ground state energy problem for TIM on a degree-3 graph is complete for the complexity class StoqMA. This is an extension of the classical class MA where the verifier can accept quantum states as a proof and apply cla...
متن کاملOn the Four-Dimensional Diluted Ising Model
8 we have found critical exponents very similar to those of the pure Ising model. We have found that the value of the critical exponents show that for lattices up to V = 32 4 the system, for p = 0:3, is not described by the mean eld theory, as one might have believed. Moreover the critical exponents that we have found are very near to those of the pure percolation. A possible explanation would ...
