Rabhi, A, Providência, C, Moszkowski, S A, Da Providência, J & Bohr, H 2021, ' Neutron stars within the Bogoliubov quark-meson coupling model ', Physical Review C, vol. 103, no. 3, 035811 . https://doi.org/10.1103/PhysRevC.103.035811
A quark-meson coupling model based on the quark model proposed by Bogoliubov for the description of the quark dynamics is developed and applied to the description of neutron stars. Starting from a su(3) symmetry approach, it is shown that this symmet

We generalize the Bogoliubov quark-meson coupling (QMC) model to also include hyperons. The hyperon-[Formula: see text]-meson couplings are fixed by the model and the hyperon-[Formula: see text]-meson couplings are fitted to the hyperon potentials in

The incompressibility (compression modulus) $K_{\rm 0}$ of infinite symmetric nuclear matter at saturation density has become one of the major constraints on mean-field models of nuclear many-body systems as well as of models of high density matter i

We introduce a generalized Yamaguchi rank-one separable potential with three parameters which has the separable Yukawa or central Yamaguchi potentials as limiting cases. The three parameters can be obtained, when possible, from the set of experimenta

We search for three-alpha resonances in C-12 by using the complex scaling method in a microscopic cluster model. All experimentally known low-lying natural-parity states are localized. For the first time we unambiguously show that the 0+_2 state in C

We calculate the strong couplings of pions to the $\ensuremath{\Delta}(1232)$ resonance using a QCD parametrization method that includes in addition to the usual one-quark also two-quark and previously uncalculated three-quark operators. We find that

The quark-meson coupling model due to Guichon is formulated on the basis of the independent quark model of the nucleon proposed by Bogoliubov and is applied to the phenomenological descriptions of symmetric and asymmetric nuclear matter. For symmetri

An extended Skyrme-Landau interaction - SL1, which includes velocity-dependent three-body forces and a tensor force is developed. Unlike the effective interactions with density-dependent two-body forces, this form of the interaction yields, in finite

The authors present deuteron wavefunctions that are radically different from the conventional ones at short distances. These wavefunctions give a value of the root mean square radius of the deuteron in agreement with the experimental result. Also, th

We consider the effects of nonlocality on the determination of the deuteron radius for model potentials. We show that the relation between the model values for the radius and the scattering length which holds for local potentials is not necessarily v
