Description
The properties of the ground state of two-color QCD at non-zero baryon chemical potential mu present an interesting problem in strongly-interacting gauge theory; in particular the nature of the physically-relevant degrees of freedom in the superfluid phase
in the high-mu regime still needs clarification. In this study we present evidence for in-medium effects at high mu by studying the wave functions
of mesonic and diquark states using orthodox lattice simulation techniques, made possible by the absence of a Sign Problem for the model with Nf=2. Our results show that beyond onset the spatial extent of hadrons decreases with mu, and are consistent with the existence of a dynamically-gapped Fermi surface in this regime.
