The Institute of Nuclear and Particle Physics (INPP) presents Jerry P. Draayer, of the Louisiana State University, presenting “Quark-gluon Plasma*” on Tuesday, Feb. 10, at at 4:00 p.m. in Edwards Accelerator Lab, Roger W. Finlay Conference Room.
Abstract: As the quark-gluon plasma – governed by strong interaction physics – cools, nucleon condensates from and cluster into nuclei that sit at the center of every atom, from hydrogen (single proton nucleus) to uranium (92 protons and 146 neutrons in its most abundant 238 isotope) and beyond. An ab initio symmetry-adapted no-core shell-model (SA-NCSM), with results that corroborate and are complementary to those first enabled studies of the structure of atomic nuclei. Applications of the theory show that bound states of light nuclei are dominated by high-deformation and low-spin configurations. The applicable symmetries, ferreted out using HPC tools, reveal the origin of collective modes – the emergence of simplicity within complexity – in such nuclei, and provide framework for determining the nature of bound states nuclei in terms of a relatively small fraction of the complete shell-model space.
