Abstract

The understanding of phase transitions has long been a fundamental problem of statistical mechanics. It has made spectac­ ular progress during the last few years, largely because of the ideas of K.G. Wilson, in applying to an apparently quite different domain the methods of the renormalization group, which had been developped in the framework of the quantum theory of fields. The ability of these theoretical methods to lead to very precise predictions has, ~n turn, stimulated in the last few years more refined experiments in different areas. We now have entered a period where the theoretical results yielded by the renormalization group approach are suffi­ ciently precise and can be compared with those of the traditional method of high temperature series expansion on lattices, and with the experimental data. Although very similar, the results coming from the renormalization group and high temperature analysis seemed to indicate systematic discrepancies between the continuous field theory and lattice models. It was therefore important to appreciate the reliability of the predictions coming from both theoretical schemes, and to compare them to the latest experimental results. We think that this Cargese Summer Institute has been very successful 1 in this respect. Indeed, leading experts in the field, both experimentalists and theoreticians, have gathered and presented detailed analysis of the present situation. In particular, B.G. Nickel has produced longer high temperature series which seem to indicate that the discrepancies between series and renormalization group results have been previously overestimated.

Physics, Percolation critical exponents, Random field, Condensed matter physics, Statistical Mechanics (cond-mat.stat-mech), Critical phenomena, FOS: Physical sciences, Square-lattice Ising model, Disordered Systems and Neural Networks (cond-mat.dis-nn), Condensed Matter - Disordered Systems and Neural Networks, Condensed Matter::Disordered Systems and Neural Networks, Dimension (vector space), Exponent, Condensed Matter::Statistical Mechanics, Ising model, Statistical physics, Critical exponent, Condensed Matter - Statistical Mechanics
Abstract

We show that current estimates of the critical exponents of the three-dimensional random-field Ising model are in agreement with the exponents of the pure Ising system in dimension 3 - theta where theta is the exponent that governs the hyperscaling violation in the random case., 9 pages, 4 encapsulated Postscript figures, REVTeX 3.0
