Title: Low-energy Gamow-Teller transitions in deformed N = Z odd-odd nuclei
Place: Meeting Room A (first floor), Center for Computational Sciences
Abstract: Low-energy Gamow-Teller transitions in deformed N = Z odd-odd nuclei (10B and 22Na) are studied by the beta-gamma AMD+GCM method with isospin projection. Roles of the pn correlation in GT transitions are discussed. Splitting of GT transition strengths occurs in 22Na because of the SU(4) symmetry breaking by the spin-orbit potential of the pn pair at the surface of 20Ne core.

Title: Nuclear pasta structures and symmetry energy
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 three-dimensional geometry with reflection symmetry. The numerical accuracy and efficiency are improved by expanding the mean fields according to fast cosine transformation and considering only one octant of the unit cell. The effect of finite cell size is treated carefully by searching for the optimum cell size. Typical pasta structures (droplet, rod, slab, tube, and bubble) arranged in various crystalline configurations are obtained for both fixed proton fractions and β-equilibration. It is found that the properties of droplets/bubbles are similar in body-centered cubic (BCC) and face-centered cubic (FCC) lattices, where the FCC lattice generally becomes more stable than BCC lattice as density increases. For the rod/tube phases, the honeycomb lattice is always more stable than the simple one. By introducing an ω-ρ cross coupling term, we further examine the pasta structures with a smaller slope of symmetry energy L = 41.34 MeV, which predicts larger onset densities for core-crust transition and non-spherical nuclei. Such a variation due to the reduction of L is expected to have impacts on various properties in neutron stars, supernova dynamics, and binary neutron star mergers.
