External Field Dependence of Deconfinement Temperature in SU(3)
Paolo Cea, Leonardo Cosmai
TL;DR
This study investigates how an external Abelian chromomagnetic field affects the deconfinement temperature in SU(3) lattice gauge theory, showing that stronger fields lower the temperature, potentially destroying confinement.
Contribution
It introduces a method using the lattice Schrödinger functional to probe SU(3) vacuum under external fields and provides preliminary evidence of the field's impact on deconfinement temperature.
Findings
Deconfinement temperature decreases with increasing external field strength.
Strong external Abelian chromomagnetic fields can destroy color confinement.
Preliminary data supports the hypothesis of field-induced deconfinement.
Abstract
We study vacuum dynamics of SU(3) lattice gauge theory at finite temperature. Using the lattice Schr\"odinger functional, SU(3) vacuum is probed by means of an external constant Abelian chromomagnetic field. Our preliminary numerical data suggest that, by increasing the strength of the applied external field, deconfinement temperature decreases towards zero. This means that strong enough Abelian chromomagnetic fields destroy confinement of color.
