abstract

According to the Hugenholtz-Van Hove theorem, nuclear symmetry energy \esym and its slope \lr at an arbitrary density $\rho$ are determined by the nucleon isovector (symmetry) potential \usym and its momentum dependence $\frac{\partial U_{sym}}{\partial k}$. The latter determines uniquely the neutron-proton effective k-mass splitting $m^*_{n-p}(\rho,\delta)\equiv (m_{\rm n}^*-m_{\rm p}^*)/m$ in neutron-rich nucleonic matter of isospin asymmetry $\delta$. Using currently available constraints on the \es0 and \l0 at normal density $\rho_0$ of nuclear matter from 28 recent analyses of various terrestrial nuclear laboratory experiments and astrophysical observations, we try to infer the corresponding neutron-proton effective k-mass splitting $m^*_{n-p}(\rho_0,\delta)$. While the mean values of the $m^*_{n-p}(\rho_0,\delta)$ obtained from most of the studies are remarkably consistent with each other and scatter very closely around an empirical value of \emass$=0.27\cdot\delta$, it is currently not possible to scientifically state surely that the \emass is positive within the present knowledge of the uncertainties. Quantifying, better understanding and then further reducing the uncertainties using modern statistical and computational techniques in extracting the \es0 and \l0 from analyzing the experimental data are much needed.

  1. Quantum van der Waals quarkyonic matter at non-zero isospin asymmetry

    nucl-th 2024-11 conditional novelty 6.0 of 10

    The authors generalize the quantum van der Waals quarkyonic matter model to asymmetric nuclear matter and find neutron star masses up to about 2.6 solar masses, with isospin-dependent repulsion preferred by observations.

  2. Investigating the possibility of extracting neutron-skin thickness in nuclei by their collisions at intermediate energies

    nucl-th 2024-11 accept novelty 5.0 of 10

    In simulated intermediate-energy tin collisions, the free neutron-to-proton yield ratio is more sensitive to the symmetry potential than to the initial neutron-skin thickness in most kinematics.

  3. Quantifying the Information Gain from Future High-Precision Radius Measurements for Identifying Twin Neutron Stars

    astro-ph.HE 2026-07 reject novelty 4.0 of 10

    The paper claims a radius precision of ~0.2 km is enough to extract most Bayesian information for identifying twin neutron stars, but its own distinguishability and entropy analyses suggest notable gains remain down t...

    IPAD-TOV is a perturbative analysis of dimensionless TOV equations yielding claimed EOS-model-independent scalings and a bound X=Pc/εc≤0.374, used to extract central EOS from NS observations.
