Description

Nuclear giant resonances provide useful constraints on nuclear equation of state (EoS). For example, the isoscalar giant monopole resonance provides direct constraint on nuclear incompressibility and the isovector modes provide useful information on symmetry energy. In this talk, I will show you the unified description of giant monopole resonance in Sn and Pb isotopes is achieved by using the quasiparticle vibration coupling approach, which solves the puzzle “Why are tins so soft?”.
Besides the giant resonances, the GW170817 neutron star merger event and the PREX-2 experiment for neutron skin measurement have provided new clues in understanding nuclear Equation of State (EoS). However, inconsistency between tidal polarizability from GW170817 event and neutron skin thickness of 208Pb R208 from PREX-2 was found based on relativistic energy density functionals (EDFs). In this talk, I will also show you how the inconsistency is reconciled.
