Probing Confinement with Chromomagnetic Fields

TL;DR

This study investigates how external chromomagnetic fields affect the confinement in SU(3) gauge theory, revealing that sufficiently strong fields can eliminate confinement by lowering the deconfinement temperature to zero.

Contribution

It demonstrates that increasing external Abelian chromomagnetic fields can destroy confinement in SU(3) gauge theory, providing insights into vacuum dynamics at finite temperature.

Findings

Deconfinement temperature decreases with stronger external fields

Strong chromomagnetic fields can eliminate confinement

Vacuum dynamics are significantly affected by external fields

Abstract

Using the lattice Schr\"odinger functional we study vacuum dynamics of SU(3) gauge theory at finite temperature. The vacuum is probed by means of an external constant Abelian chromomagnetic field. We find that by increasing the strength of the applied external field the deconfinement temperature decreases towards zero. This implies that strong enough Abelian chromomagnetic fields destroy confinement of color.
