Pion Fields and Quarks in Nuclear Matter

While the basic description of nuclear matter is usually in terms of point nucleons interacting via two-body potentials*, other degrees of freedom can be important in determining the properties of the matter. Recently the effects of nucleon isobar, or Δ (1236), degrees of freedom on the effective nucleon-nucleon interaction in matter have been stressed (Green 1976, Holinde et al. 1977, 1978). In these lectures I would like to describe the roles of explicit pion and quark degrees of freedom in producing unusual states of nuclear matter, concentrating particularly on the possibilities of pion condensation, and formation of quark matter, in the density range from normal nuclear matter density, no ≃ 0.17 fm-3, to several orders of magnitude higher.
