High momentum components in the nuclear symmetry energy
Arianna Carbone, Artur Polls, Arnau Rios
TL;DR
This paper investigates how high-momentum components caused by nucleon-nucleon correlations affect the nuclear symmetry energy, revealing a significant reduction in the kinetic part due to these correlations.
Contribution
It provides a detailed analysis of the impact of high-momentum components on the symmetry energy using realistic interactions with various short-range and tensor structures.
Findings
Kinetic symmetry energy is strongly reduced by correlations.
High-momentum components significantly influence bulk properties of asymmetric nuclear matter.
Realistic interactions with different structures elucidate the origin of this behavior.
Abstract
The short-range and tensor correlations associated to realistic nucleon-nucleon interactions induce a population of high-momentum components in the many-body nuclear wave function. We study the impact of such high-momentum components on bulk observables associated to isospin asymmetric matter. The kinetic part of the symmetry energy is strongly reduced by correlations when compared to the non-interacting case. The origin of this behavior is elucidated using realistic interactions with different short-range and tensor structures.
