Magnetic component of Yang-Mills plasma

Area of Science:

• High-energy physics
• Quantum field theory
• Confinement in non-Abelian gauge theories

Background:

• Confinement in non-Abelian gauge theories is often explained by the percolation of magnetic monopoles or vacuum strings.
• The deconfinement phase transition releases condensed magnetic degrees of freedom as thermal magnetic monopoles into the gluon plasma.

Purpose of the Study:

• To utilize lattice simulations within the percolation picture to estimate the monopole content of the gluon plasma.
• To investigate the behavior of monopole density in the gluon plasma around the critical temperature.

Main Methods:

• Lattice simulations were employed to model non-Abelian gauge theories.
• The percolation picture was used to analyze the role of magnetic monopoles.
• Monopole density was calculated and analyzed as a function of temperature relative to the critical temperature.

Main Results:

• Lattice simulations provide a method to estimate monopole density in the gluon plasma.
• Above the critical temperature, the monopole density initially remains constant, similar to a liquid.
• As temperature further increases, the monopole density begins to grow, characteristic of a gas.

Conclusions:

• The percolation picture offers a framework for understanding monopole behavior in the gluon plasma.
• The observed density behavior suggests a phase transition in monopole characteristics from liquid-like to gas-like above the deconfinement temperature.
