Novel methods for determining effective interactions for the nuclear shell model

Novel Methods for Determining Effective Interactions for the Nuclear Shell Model

The Contractor Renormalization (CORE) method is applied in combination with modern effective-theory techniques to the nuclear many-body problem. A one-dimensional—yet “realistic”—nucleon-nucleon potential is introduced to test these novel ideas. It is found that the magnitude of “model-space” (CORE) corrections diminishes considerably when an effective potential that eliminates the hard-momentu...

Effective interactions for the nuclear shell model

Various perturbative and non-perturbative many-body techniques are discussed in this work. Especially, we will focus on the summation of so-called Parquet diagrams with emphasis on applications to finite nuclei. Here, the subset of two-body Parquet equations will be discussed. A practical implementation of the corresponding equations for studies of effective interactions for finite nuclei is ou...

Effective Interactions for the Nuclear Shell Model

EfFective interactions for the OplsOd nuclear shell - madel space

Shell-model interactions are constructed in the cross-shell model space connecting the Op and ls0d shells with due regard for the perturbative efFects of the neighboring Os and Oflp shells. The interactions have three distinctive Op-shell, cross-shell, and 1sOd-shell parts. The latter is taken to be the previously determined W interaction. The Op-shell interaction is represented by two-body mat...
