The p - n pairs correlations of the hot asymmetric nucleonic matter in the LOCV approach

The state-and operator-dependent nucleon-nucleon correlations of hot asymmetric nucleonic matter (ASM) are studied in the lowest order constrained variational (LOCV) framework. It is observed that at low temperatures, proton to neutron ratios, and densities, the p - n pairs in the 3S1 -3 D1 and 3P2 -3 F2 coupled channels become more non-centrally correlated. In the 3P2-3F2 channel, p-n pairs lose their non-central correlations at shorter inter-particle distances, especially at higher proton to neutron ratios, compared to the case of 3S1 -3 D1 channel. By increasing the proton to neutron ratio and temperature, the tensor correlation range of p - n pairs in the 3S1 -3 D1 channel becomes short. It is illustrated that the choice of the non-central correlation, i.e., the spin-orbit or tensor correlations, in the 3P2-3 F2 channel plays an important role in the ASM energy, specifically at small proton to neutron ratios and high temperatures.

Automated summary

The state-and operator-dependent nucleon-nucleon correlations of hot asymmetric nucleonic matter (ASM) were studied in the lowest order constrained variational (LOCV) framework. It was observed that the p-n pairs in specific channels become more non-centrally correlated at low temperatures, proton to neutron ratios, and densities. The choice of non-central correlation in the channels plays an important role in the energy of ASM.
