Manifestations of magnetic vortices in equation of state of Yang-Mills plasma

Understand

The vacuum of Yang-Mills theory contains singular stringlike objects identified with center (magnetic) vortices.

• Percolation of magnetic vortices is known to be responsible for the color confinement in the low-temperature phase of the theory.
• In our work we study properties of the vortices at finite temperature using lattice simulations of SU(2) gauge theory.
• We show that magnetic vortices provide a numerically large contribution to thermodynamic quantities of the gluon plasma in Yang-Mills theory.
