Dynamical generation of a gauge symmetry in the Double-Exchange model
J. M. Carmona, A. Cruz, L. A. Fernandez +7
It is shown that a bosonic formulation of the double-exchange model, one of the classical models for magnetism, generates dynamically a gauge-invariant phase in a finite region of…
Deconfining transition in Full QCD
J. M. Carmona, M. D'Elia, L. Del Debbio +4
We present evidence that in full QCD with two dynamical quarks confinement is produced by dual superconductivity of the vacuum as in the quenched theory. Preliminary information is…
Color confinement and dual superconductivity in unquenched QCD
J. M. Carmona, M. D'Elia, L. Del Debbio +4
We report on evidence from lattice simulations that confinement is produced by dual superconductivity of the vacuum in full QCD as in quenched QCD. Preliminary information is obtai…
Color confinement and dual superconductivity in full QCD
J. M. Carmona, M. D'Elia, L. Del Debbio +3
We report on evidence that confinement is related to dual superconductivity of the vacuum in full QCD, as in quenched QCD. The vacuum is a dual superconductor in the confining phas…
Dual Superconductivity and Chiral Symmetry in Full QCD
J. M. Carmona, M. D'Elia, L. Del Debbio +3
A disorder parameter detecting dual superconductivity of the vacuum is measured across the chiral phase transition in full QCD with two flavours of dynamical staggered fermions. Th…
A disorder analysis of the Ising model
J. M. Carmona, A. Di Giacomo, B. Lucini
Lattice studies of monopole condensation in QCD are based on the construction of a disorder parameter, a creation operator of monopoles which is written in terms of the gauge field…
Implementation of C* boundary conditions in the Hybrid Monte Carlo algorithm
J. M. Carmona, M. D'Elia, A. Di Giacomo +1
In the study of QCD dynamics, C* boundary conditions are physically relevant in certain cases. In this paper we study the implementation of these boundary conditions in the lattice…
Is trivial the antiferromagnetic RP(2) model in four dimensions?
H. G. Ballesteros, J. M. Carmona, L. A. Fernandez +3
We study the antiferromagnetic RP(2) model in four dimensions. We find a second order transition with two order parameters, one ferromagnetic and the other antiferromagnetic. The a…
Antiferromagnetism in four dimensions: search for non-triviality
J. L. Alonso, H. G. Ballesteros, I. Campos +8
We present antiferromagnetism as a mechanism capable of modifying substantially the phase diagram and the critical behaviour of statistical mechanical models. This is particularly…
