Effect of nucleon correlations on pion condensation in neutron stars
Abstract
It is pointed out that nucleon-nucleon correlations, play an important role in the pion condensation problem. Their effect is estimated by a simple analytical method. It is seen that they inhibit condensation by reducing the attraction a pion might otherwise feel in nuclear matter. Further the effect of correlations increases with nucleon density ϱ, offsetting the corresponding increase in the attraction felt by pions in free neutron matter.
