Vortex structure of the vacuum and confinement
T. G. Kovács, E. T. Tomboulis
Abstract
We discuss the recently published numerical computations of the vortex free energy. They dramatically demonstrate that the excitation probability for a sufficiently thick vortex approaches unity at large beta, i.e. that thick vortices `condense' in the vacuum. This is known to imply confinement. An analytical approach for exploring this phenomenon is also outlined.
