Field-theory results for three-dimensional transitions with complex symmetries
Pasquale Calabrese, Andrea Pelissetto, Paolo Rossi +1
We discuss several examples of three-dimensional critical phenomena that can be described by Landau-Ginzburg-Wilson theories. We present an overview of field-theoretical resu…
Transverse Fluctuations in the Driven Lattice Gas
Sergio Caracciolo, Andrea Gambassi, Massimiliano Gubinelli +1
We define a transverse correlation length suitable to discuss the finite-size-scaling behavior of an out-of-equilibrium lattice gas, whose correlation functions decay algebraically…
Multicritical phenomena in O(n_1)+O(n_2)-symmetric theories
Pasquale Calabrese, Andrea Pelissetto, Ettore Vicari
We study the multicritical behavior arising from the competition of two distinct types of ordering characterized by O(n) symmetries. For this purpose, we consider the renormalizati…
Critical behavior of vector models with cubic symmetry
P. Calabrese, A. Pelissetto, E. Vicari
We report on some results concerning the effects of cubic anisotropy and quenched uncorrelated impurities on multicomponent spin models. The analysis of the six-loop three-dimensio…
Comment on ``Bicritical and Tetracritical Phenomena and Scaling Properties of the SO(5) Theory,'' [X. Hu, Phys. Rev. Lett. 87, 057004 (2001)]
Pasquale Calabrese, Andrea Pelissetto, Ettore Vicari
We show that, in the most general -component theory with symmetry O(n_1)+O(n_2), N=n_1+n_2\geq 3, the O(N)-symmetric fixed point has (at least) three unstable directions: the te…
Two-Dimensional Heisenberg Model with Nonlinear Interactions
Sergio Caracciolo, Andrea Pelissetto
We investigate a two-dimensional classical -vector model with a nonlinear interaction $(1 + \bsigma_i\cdot \bsigma_j)^p$ in the large-N limit. As observed for N=3 by Blöte {\em…
Critical structure factor in Ising systems
Victor Martin-Mayor, Andrea Pelissetto, Ettore Vicari
We perform a large-scale Monte Carlo simulation of the three-dimensional Ising model on simple cubic lattices of size L^3 with L=128 and 256. We determine the corresponding structu…
Randomly dilute spin models with cubic symmetry
Pasquale Calabrese, Andrea Pelissetto, Ettore Vicari
We study the combined effect of cubic anisotropy and quenched uncorrelated impurities on multicomponent spin models. For this purpose, we consider the field-theoretical approach ba…
Equation of state for systems with Goldstone bosons
Massimo Campostrini, Martin Hasenbusch, Andrea Pelissetto +2
We discuss some recent determinations of the equation of state for the XY and the Heisenberg universality class.
25th-order high-temperature expansion results for three-dimensional Ising-like systems on the simple cubic lattice
Massimo Campostrini, Andrea Pelissetto, Paolo Rossi +1
25th-order high-temperature series are computed for a general nearest-neighbor three-dimensional Ising model with arbitrary potential on the simple cubic lattice. In particular, we…
