Mean-field expansion for spin models with medium-range interactions
We study the critical crossover between the Gaussian and the Wilson-Fisher fixed point for general O(N)-invariant spin models with medium-range interactions. We perform a systematic expansion around the mean-field solution, obtaining the universal crossover curves and their leading corrections. In particular we show that, in three dimensions, the leading correction scales as R−3, R being the ra...

متن کاملbaryon-baryon interactions in chiral effective field theory
We have constructed the leading order strangeness S = −1,−2 baryon-baryon potential in a chiral effective field theory approach. The chiral potential consists of one-pseudoscalar-meson exchanges and non-derivative four-baryon contact terms. The potential, derived using SU(3) f symmetry constraints, contains six independent low-energy coefficients. We have solved a regularized Lippmann-Schwinger...
متن کاملbaryon-baryon interactions using chiral effective field theory
We derive the leading order strangeness S = −2 baryon-baryon interactions in chiral effective field theory. The potential consists of contact terms without derivatives and of one-pseudoscalar-meson exchanges. The contact terms and the couplings of the pseudoscalar mesons to the baryons are related via SU(3)f symmetry to the S = −1 hyperonnucleon channels. We show that the chiral effective field...
متن کاملMean field theory of spin glasses
These lecture notes have been prepared for a course in Trieste, part of the Ph.D. program in Statistical Mechanics. They focus on the mean field theory of spin glasses, with particular emphasis on the presence of a very large number of metastable states in these systems. This phenomenon, and some of its physical consequences, will be discussed in details for fully-connected models and for model...
