Two-colour QCD with heavy quarks at finite densities

Understand

We extend the density-of-states approach to gauge systems (LLR method) to QCD at finite temperature and density with heavy quarks.

• The approach features an exponential error suppression and yields the Polyakov loop probability distribution function over a range of more than hundred orders of magnitude.
• SU(2) gauge theory is considered in the confinement and the high-temperature phase, and at finite densities of heavy quarks.
• In the latter case, a smooth rise of the density with the chemical potential is observed, and no critical phenomenon associated with deconfinement due to finite densities is found.
