    "abstract": "A non-perturbative s-wave renormalization of the pion in a hot and baryon\nrich medium is presented. This approach proceeds via a mapping of the canonical\npion into the axial Noether\u0027s charge. The mapping was made dynamical in the\nHartree-Fock-Bogoliubov random phase approximation (HFB-RPA). It is shown that\nthis approach, while order mixing, is still symmetry conserving both in the\nbaryon free and baryon rich sectors, at zero as well as finite temperature. The\nsystematic character of this approach is emphasized and it is particularly\nargued that it may constitute an interesting alternative for the\nnon-perturbative assessment of the nuclear matter saturation properties.",
