Flux tube profiles in two-color QCD at low temperature and high density
May 16, 2022
We investigate the temperature and density dependence of the color flux tube structure of dense two-color QCD with 𝑁𝑓 = 2 Wilson fermions by using a lattice simulation. From Refs.  and , we have already clarified the rich phase structure in the low temperature region, including the hadronic and superfluid phases. In this study we measure the quark-antiquark potential and color flux tube profiles in such a low temperature region and find that even in the high density superfluid phase, the color electric field is squeezed into a flux tube as in the low density hadronic phase.
