Critical Phenomena and Renormalization-Group Theory
Andrea Pelissetto, Ettore Vicari
We review results concerning the critical behavior of spin systems at equilibrium. We consider the Ising and the general O()-symmetric universality classes, including the $N\to…
Finite-Size Correlation Length and Violations of Finite-Size Scaling
Sergio Caracciolo, Andrea Gambassi, Massimiliano Gubinelli +1
We address the problem of the definition of the finite-volume correlation length. First, we study the large-N limit of the N-vector model, and we show the existence of several cons…
Critical behavior of the three-dimensional XY universality class
Massimo Campostrini, Martin Hasenbusch, Andrea Pelissetto +2
We improve the theoretical estimates of the critical exponents for the three-dimensional XY universality class. We find alpha=-0.0146(8), gamma=1.3177(5), nu=0.67155(27), eta=0.038…
The critical behavior of frustrated spin models with noncollinear order
Andrea Pelissetto, Paolo Rossi, Ettore Vicari
We study the critical behavior of frustrated spin models with noncollinear order, including stacked triangular antiferromagnets and helimagnets. For this purpose we compute the fie…
Linked-Cluster Expansion of the Ising Model
Massimo Campostrini
The linked-cluster expansion technique for the high-temperature expansion of spin model is reviewed. A new algorithm for the computation of three-point and higher Green's functions…
Randomly dilute spin models: a six-loop field-theoretic study
A. Pelissetto, E. Vicari
We consider the Ginzburg-Landau MN-model that describes M N-vector cubic models with O(M)-symmetric couplings. We compute the renormalization-group functions to six-loop order in d…
