Query: Density dependence of symmetry energy and neutron skin thickness
  revisited using relativistic mean field models with nonlinear couplings   The correlation between neutron skin-thickness of a neutron-rich nucleus and
slope parameter of symmetry energy is assessed as a function of density using
relativistic mean field models containing non-linear couplings among different
mesons. Models with larger skin were found to probe the slope parameter even at
suprasaturation densities, whereas models with smaller skin were observed to be
sensitive only at specific subsaturation density, connected to the average
density of nuclei. Possible reasons behind this density dependence are explored
systematically. These results might be model specific, which need to be
reassessed in other type of interactions existing in the literature.
Nevertheless, extrapolating the predictions at high densities from models,
which are optimized by data at saturation or subsaturation densities, needs to
be handled with care.
