${}^1{S}_0$ pairing for neutrons in dense neutron matter induced by a soft pion

S. S. Pankratov, M. Baldo, E. E. Saperstein

The possibility of neutron pairing in the ${}^1{S}_0$ channel is studied for dense neutron matter in a vicinity of the ${\pi }^0$ condensation point. The ${}^1{S}_0$ pairing gap $\Delta$ is shown to…
