Abstract

The saturation properties of the nuclear matter taking pion correlations into account are studied. We construct a Bogoliubov transformation for the pion pair operators and calculate the energy associated with the pion pairs. The pion dispersion relation is investigated. The correlation energy due to one-pion exchange in nuclear matter and neutron matter at random phase approximation using the generator coordinate method is also studied. The techniques of the charged pion correlations are discussed in the neutron matter calculations. We observe that there is no sign of the pion condensation in this model.
