On the evaluation of the improvement parameter in the lattice Hamiltonian approach to critical phenomena

Massimo Campostrini, Pietro Parruccini, Paolo Rossi

In lattice Hamiltonian systems with a quartic coupling $γ$ , a critical value $γ^{*}$ may exist such that, when $γ = γ^{*}$ , the leading irrelevant operator decouples from the Hamiltonian…

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…

Chiral critical behavior in two dimensions from five-loop renormalization-group expansions

P. Calabrese, E. V. Orlov, P. Parruccini +1

We analyse the critical behavior of two-dimensional N-vector spin systems with noncollinear order within the five-loop renormalization-group approximation. The structure of the RG…

Chiral phase transitions: focus driven critical behavior in systems with planar and vector ordering

P. Calabrese, P. Parruccini, A. I. Sokolov

The fixed point that governs the critical behavior of magnets described by the $N$ -vector chiral model under the physical values of $N$ ( $N = 2, 3$ ) is shown to be a stable focus bo…

Two-Dimensional Heisenberg Model with Nonlinear Interactions

Sergio Caracciolo, Andrea Pelissetto

We investigate a two-dimensional classical $N$ -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…
