Disappearance of the Abrikosov vortex above the deconfining phase transition in SU(2) lattice gauge theory

TL;DR

This study investigates how magnetic monopole currents and electric flux distributions change across the deconfining phase transition in SU(2) lattice gauge theory, revealing a disappearance of the Abrikosov vortex above the transition.

Contribution

It provides the first detailed lattice simulation of monopole currents and flux distributions across the deconfining transition in SU(2) gauge theory, confirming theoretical predictions.

Findings

Monopole currents and flux distributions differ significantly below and above the transition.

Results align with Ginzburg-Landau effective theory predictions.

The Abrikosov vortex disappears above the deconfining phase transition.

Abstract

We calculate the solenoidal magnetic monopole current and electric flux distributions at finite temperature in the presence of a static quark antiquark pair. The simulation was performed using SU(2) lattice gauge theory in the maximal Abelian gauge. We find that the monopole current and electric flux distributions are quite different below and above the finite temperature deconfining phase transition point and agree with predictions of the Ginzburg-Landau effective theory.
