Abstract

We study SU(2) Lattice Gauge Theory with dynamical fermions at non-zero chemical potential μ. The symmetries special to SU(2) for staggered fermions on the lattice are discussed explicitly and their relevance to spectroscopy and condensates at non-zero chemical potential are considered. Using the molecular dynamics algorithm on small lattices we find qualitative changes in the theory's spectroscopy at small and large values of μ. This preliminary study should lay the groundwork for future large scale simulations.
