Lorenz von Smekal (1), with Philippe de Forcrand (2) ((1) University, Erlangen-Nuremberg, (2) ETH Zurich, CERN)
TL;DR
This paper investigates electric and magnetic fluxes in SU(2) Yang-Mills theory, measuring free energies of static charges and monopoles to understand their roles in deconfinement and phase transitions.
Contribution
It provides the first detailed measurement of free energies for static charges and monopoles in SU(2) Yang-Mills theory, clarifying their relevance to deconfinement.
Findings
Electric fluxes serve as order parameters for deconfinement.
Monopole free energies vanish at all temperatures, indicating irrelevance for the transition.
Static fundamental charges exhibit well-defined free energies related to deconfinement.
Abstract
We measure the free energies in SU(2) of static fundamental charges and center monopoles. Dual to temporal center fluxes, the former provide a well-defined (dis)order parameter for deconfinement. In contrast, the monopole free energies vanish in the thermodynamic limit at all temperatures and are thus irrelevant for the transition.
