Thermal Transitions in Dense Two-Colour QCD

The infamous sign problem makes it impossible to probe dense (baryon density μB > 0) QCD at temperatures near or below the deconfinement threshold. As a workaround, one can explore QCD-like theories such as twocolour QCD (QC2D) which don’t suffer from this sign problem but are qualitively similar to real QCD. Previous studies on smaller lattice volumes have investigated deconfinement and colour superfluid to normal matter transitions. In this study we look at a larger lattice volume Ns = 24 in an attempt to disentangle finite volume and finite temperature effects. We also fit to a larger number of diquark sources to better allow for extrapolation to zero diquark source.
