External Fields and Color Confinement

U(1), SU(2), and SU(3) lattice gauge theories in presence of external fields are investigated both in (3+1) and (2+1) dimensions. The free energy of gauge systems has been measured. While the phase transition in compact U(1) is not influenced by the strength of an external constant magnetic field, the deconfinement temperature for SU(2) and SU(3) gauge systems in a constant abelian chromomagnet...

Color Confinement and Massive Gluons

It is shown that there are two phases in QCD distinguished by different choices of the gauge parameter. In one phase, called the ”confined phase”, color confinement is realized and gluons turn out to be massive. In the other phase, called the ”deconfined phase”, color confinement is not realized, but the gluons remain massless.

A simple solution to color confinement

We show that color confinement is a direct result of the nonabelian, i.e. nonlinear, nature of the color interaction in quantum chromodynamics. This makes it in general impossible to describe the color field as a collection of elementary quanta (gluons). A quark cannot be an elementary quanta of the quark field, as the color field of which it is the source is itself a source hence making isolat...

Confinement versus color superconductivity: a lattice investigation

The QCD phase diagram as function of the temperature and the baryon chemical potential is the object of many theoretical and experimental investigations. At a high chemical potential, QCD is in the deconfined phase with quarks forming a Fermi surface. It turns out that the gluon induced quark interaction is attractive in the diquark channel [1] generating a Cooper instability of the Fermi surfa...

A Dynamical Model of Color Confinement *

A dynamical model of confinement based on a transport theoretical description of the Friedberg-Lee model is extended to explicit color degrees of freedom. The string tension is reproduced by an adiabatic string formation from the nucleon ground state. Color isovector oscillation modes of a q ¯ q-system are investigated for a wide range of relative q ¯ q-momenta and the dynamical impact of color...
