We evoke the possible existence of hypercollapsed tightly bound nuclear isomers, due to the existence of an attractive ‘heart’ deep inside the repulsive core.

Using a nucleon–nucleon force of the type M3Y-Reid and an additional repulsive interaction which simulates the incompressibility effects of the nuclear matter, we have examined the effects of the repulsive core modeling on the interaction potentials and complete fusion cross-sections for 9 Be + 124 Sn and 9 Be + 89 Y systems. The adjusted parameters of this repulsive force have been chosen in such a way that fully explains the properties of the nuclear matter in the region where the nuclear densities of the interacting nuclei completely overlap. The results of our studies reveal that accounting for this correction in the calculations of the total potentials leads to improvement of calculated cross-sections and affects on the complete fusion suppression at above barrier energies.

AbstractTopology effects have being extensively studied and confirmed in strongly correlated condensed matter physics. In the limit of large number of colors, baryons can be regarded as topological objects—skyrmions—and the baryonic matter can be regarded as a skyrmion matter. We review in this paper the generalized effective field theory for dense compact-star matter constructed with the robust inputs obtained from the skyrmion approach to dense nuclear matter, relying on possible “emergent” scale and local flavor symmetries at high density. All nuclear matter properties from the saturation density n0 up to several times n0 can be fairly well described. A uniquely novel—and unorthdox—feature of this theory is the precocious appearance of the pseudo-conformal sound velocity $v^{2}_{s}/c^{2} \approx 1/3$ v s 2 / c 2 ≈ 1 / 3 , with the non-vanishing trace of the energy momentum tensor of the system. The topology change encoded in the density scaling of low energy constants is interpreted as the quark-hadron continuity in the sense of Cheshire Cat Principle (CCP) at density $\gtrsim 2n_{0}$ ≳ 2 n 0 in accessing massive compact stars. We confront the approach with the data from GW170817 and GW190425.
