Mean-field approximations and multipartite thermal correlations
The relationship between the mean-field approximations in various interacting models of statistical physics and measures of classical and quantum correlations is explored. We present a method that allows us to find an upper bound for the total amount of correlations (and hence entanglement) in a physical system in thermal equilibrium at some temperature in terms of its free energy and internal ...

متن کاملClamping Improves TRW and Mean Field Approximations
We examine the effect of clamping variables for approximate inference in undirected graphical models with pairwise relationships and discrete variables. For any number of variable labels, we demonstrate that clamping and summing approximate sub-partition functions can lead only to a decrease in the partition function estimate for TRW, and an increase for the naive mean field method, in each cas...
متن کاملBelief Propagation, Mean-field, and Bethe approximations
This chapter describes methods for estimating the marginals and maximum a posteriori (MAP) estimates of probability distributions defined over graphs by approximate methods including Mean Field Theory (MFT), variational methods, and belief propagation. These methods typically formulate this problem in terms of minimizing a free energy function of pseudomarginals. They differ by the design of th...
متن کاملAccuracy of Mean Field Approximations for Atomsand
We estimate the accuracy of the mean eld approximation induced by the Thomas-Fermi potential for the ground state energy of atoms and molecules. Taking the Dirac exchange correction into account, we show the error to be of the form O(Z 5=3?) + D for any < 2=231 as the total nuclear charge Z becomes large. D is an electrostatic energy of the diierence density that measures the deviation of the m...
