We investigate the linear-chain configurations of four-$\alpha$ clusters in $^{16}$O using a Skyrme cranked Hartree-Fock method and discuss the relationship between the stability of such states and an...
Scalar field in nuclear matter: the roles of spontaneous chiral symmetry breaking and nucleon structure
nuclear matter roles of spontaneous chiral symmetry breaking nucleon structure

Chiral theories with spontaneous symmetry breaking such as the Nambu-Jona-Lasinio (NJL)
model lead to the existence of a scalar mode. We present in a detailed manner how the corresponding low momentu...
