Kohn-Luttinger effect in dense matter and its implications for neutron stars
Repulsive short-range interactions can induce $p$-wave attraction between fermions in dense matter and lead to Cooper pairing at the Fermi surface. We investigate this phenomenon, well known as the Kohn-Luttinger effect in condensed-matter physics, in dense matter with strong short-range repulsive interactions. We find that repulsive interactions required to stabilize …
