A new mechanism of mass protection for fermions
J. L. Alonso, Ph. Boucaud, J. M. Carmona +3
We present a way of protecting a Dirac fermion interacting with a scalar (Higgs) field from getting a mass from the vacuum. It is obtained through an implementation of translationa…
Phase-diagram and quasiparticles of a lattice SU(2) scalar-fermion model in (2+1) dimensions
J. L. Alonso, Ph. Boucaud, V. Martin-Mayor +1
The phase diagram at zero temperature of a lattice SU(2) scalar-fermion model in (2+1) dimensions is studied numerically and with Mean-Field methods. Special attention is devoted t…
Laplacian Abelian Projection: Abelian dominance and Monopole dominance
A. J. van der Sijs
A comparative study of Abelian and Monopole dominance in the Laplacian and Maximally Abelian projected gauges is carried out. Clear evidence for both types of dominance is obtained…
Mass protection via translational invariance
J. L. Alonso, Ph. Boucaud, J. M. Carmona +3
We propose a way of protecting a Dirac fermion interacting with a scalar field from acquiring a mass from the vacuum. It is obtained through an implementation of translational symm…
Abelian Projection without Ambiguities
A. J. van der Sijs
Laplacian Abelian Projection is discussed. This term refers to the use of a new (``Laplacian'') gauge fixing prescription for implementing the Abelian Projection of QCD. The gauge…
Three topics in the Schwinger model
Ph. de Forcrand, J. E. Hetrick, T. Takaishi +1
1. We compare Monte Carlo results with analytic predictions for the fermion condensate, in the massive one-flavour Schwinger model. 2. We illustrate on the Schwinger model how to f…
