Title: Progress in the First Principles Calculation of Nuclear Structure Observables
Abstract: In the past decade, concurrent advances in nuclear interactions, many-body methods, and computational power have launched an explosive foray into ab-initio calculation of nuclear structure properties. Until recently, such calculations were limited only to nuclei with the lightest masses (A < 10). The development of renormalization group (RG) methods designed to exploit momentum scale separation in the nuclear many-body problem have made extension of ab-initio methods to the medium mass regime possible. This work focuses on the application of the fledgling in-medium similarity renormalization group (IM-SRG) method to calculate excited-state properties, such as energies and transition strengths, in a consistent effective operator framework. This particular variant of IM-SRG employs equations of motion (EOM) methods to extract excited state structure from the IM-SRG effective operators.
