Abstract

We calculate the meson screening mass in a pion superfluid in the framework of Nambu–Jona-Lasinio model. The minimum of the attractive quark potential is always located at the phase boundary of pion superfluid. Different from the temperature and baryon density effect, the potential at finite isospin density cannot be efficiently suppressed and the matter is always in a strongly coupled phase due to the Goldstone mode in the pion superfluid.
