    "abstract": "We consider a new approach to the description of dense nuclear matter in the\nframework of chirally symmetric, quark-based hadron models. As previously in\nthe Skyrme model, the dense environment is described in terms of hyperspherical\ncells of unit baryon number. The intrinsic curvature of these cells generates a\nnew gauge interaction for the quark fields which mediates interactions with the\nambient matter. We apply this approach to the Nambu-Jona-Lasinio (NJL) model,\nconstruct its curved-space quark propagator and solve the ladder Bethe-Salpeter\nequation for the pion. We find a high-density phase transition to chiral\nrestoration, discuss the density dependence of the chiral order parameter and\nof the pion properties, and compare with results of the conventional\nchemical-potential approach. The new approach can additionally describe\nbaryon-density-free cavities in the dense medium.",
