The Weak Entanglment Approximation for Nuclear Stucture
ORAL
Abstract
The configuration-interaction shell model is a useful and insightful tool for nuclear structure, but basis dimensions limit the model space. Building upon recent observations
that the proton and neutron partitions of shell-model wave functions are weakly entangled, we have developed a 'weak entanglement approximation' which efficiently constructs a basis for large-scale shell model calculations, including in model spaces far beyond what current codes can reach. We will present examples in large model spaces and discuss the future prospects of this approximation.
