What the literature leaves open
The study is based on theoretical calculations and lacks experimental verification, - The RETF formalism is a semi-classical approximation and lacks detailed structure of the nucleus, - The study only considers a limited range of superheavy nuclei with atomic numbers Z = 110-118
The properties of superheavy elements are not experimentally well known due to their short lifetime and difficulties in the synthesis process. There is a need for a thorough theoretical understanding of the nature of these superheavy elements. The existing theoretical models have limitations in predicting the properties of superheavy elements.

PHASE NUCLEAR PHYSICS From the proton-proton cycle to the "island of stability" within the framework of chronal dynamics · 2026 · DOIFurther study of the implications of short-range correlations for the equation of state of dense matter is needed. The development of more accurate models of nuclear reactions and astrophysical phenomena that incorporate short-range correlations is necessary. The application of the results of this paper to the study of neutron star properties and behavior is a potential area of future research.
Nucleon short-range correlations and high-momentum dynamics: implications on the equation of state of dense matter · 2026 · DOIIts generalization to higher densities, rele- vant for NS interiors [35], relies on assumptions that remain to be critically examined. In particular, the physical basis for the assumed DM distribution and interactions in two-fluid RMF models is largely phenomenological, and the detailed mechanism by which DM is captured and accumulates inside NSs is still an open question. 6 Summary, open questions, and future perspectives This review has summarized recent progress in understanding how nucleon short-range correlations and the associ- ated high-momentum tail in the single-nucleon momentum distribution influence the EOS of dense nuclear matter, with broad implications for neutron stars and heavy-ion collisions (HICs). Below we outline several necessary refinements and open problems whose resolution would advance our understanding of SRC-HMT physics in NSs and HICs, as well as in nuclear many-body theory more broadly. In other words, an important open question is whether one can reliably constrain HMT properties, such as the neutron–proton or proton–proton SRC ratio at high densities, using self-consistent theoretical approaches or experimentally validated methods.
Nucleon short-range correlations and high-momentum dynamics: implications on the equation of state of dense matter · 2026 · DOIThe study only considers a limited range of astrophysical conditions. The finite-temperature β-decay rates are only calculated for nuclei with proton numbers 20 ≤ Z ≤ 60.
The calculations were performed with fixed heating efficiency parameters, but the actual heating efficiency in real astrophysical r-process events (neutron star mergers, core-collapse supernovae) remains observationally unconstrained. Connecting theoretical heating efficiency values used in reaction network calculations to observational constraints from kilonova electromagnetic signatures requires dedicated investigation.
