演題：Nuclear “pasta” structures and symmetry energy
場所：※オンラインセミナー

概要(Abstract)： In the framework of the relativistic mean field model with Thomas-Fermi approximation, we study the structures of low density nuclear matter in a fully three-dimensional geometry. Typical pasta structures (droplet, rod, slab, tube, and bubble) arranged in various crystalline configurations are obtained for both fixed proton fraction and cold catalyzed matter. By introducing an ω-ρ cross coupling term, we further examine the pasta structures with smaller symmetry energy slope L = 41.34 MeV, which is consistent with various constrains from nuclear physics and pulsar observations.
