Figure 1

Neutron, proton, and lambda chemical potentials at zero pressure as a function of the nucleon asymmetry for different values of ${\rho }_{\Lambda }$, obtained with the SLy4 interaction together with the parametrization of Eq. (5). ${\mu }_n$ and ${\mu }_p$ are shown in the left panel, while ${\mu }_{\Lambda }$ is plotted in the right panel. The solid, dotted, and dashed lines correspond to ${\rho }_{\Lambda }=$ 0.0, 0.02, and 0.04 ${\mathrm{fm}}^{-3}$, respectively.Reuse & Permissions

Figure 2

Total baryon density at zero pressure as a function of the nucleon asymmetry for different values of ${\rho }_{\Lambda }$, obtained with the SLy4 interaction for the nucleonic energy density. Going from low to high densities, the different curves correspond to ${\rho }_{\Lambda }=0.0,0.01,0.02,0.03,0.04\hspace{0.5em}{\mathrm{fm}}^{-3}$.Reuse & Permissions

Upper panel: Energy of the highest (partially) occupied neutron $1d_{5/2}$ single-particle level of several beryllium isotopes containing no (solid lines) or two (dotted lines) $\Lambda$'s. Deformed (black) and undeformed (green) SHF calculations with the SLy4 force are compared. Lower panel: Quadrupole deformation of the (hyper)nucleus.Reuse & Permissions
