Dense two-color QCD from Dyson-Schwinger equations

Understand

We investigate quantum chromodynamics with two colors at nonvanishing density using Dyson-Schwinger equations.

• Lattice methods do not have a complex action problem in this theory.
• Thus, we can benchmark our results and the effect of truncations directly by comparing with the corresponding lattice results.
• We do so for the gluon propagator, the chiral condensate, and the quark number density and test variations of the employed truncation to improve the agreement.
