Emergent chirality and superfluidity of parity-doubled baryons in neutron stars

Shigehiro Yasui, Muneto Nitta, Chihiro Sasaki

We propose novel superfluids induced by the parity-doubled baryons. The parity-doubled baryons, i.e., a nucleon $N(940)$ with spin-parity $J^P=1/2^{+}$ and an excited nucleon $N^…
