Title: Ab initio no-core Gamow shell model calculations with realistic interactions

Abstract

No-Core Gamow Shell Model (NCGSM) is applied for the first time to study selected well-bound and unbound states of helium isotopes. This model is formulated on the complex energy plane and, by using a complete Berggren ensemble, treats bound, resonant, and scattering states on equal footing. We use the Density Matrix Renormalization Group method to solve the many-body Schrödinger equation. To test the validity of our approach, we benchmarked the NCGSM results against Faddeev and Faddeev-Yakubovsky exact calculations for 3H and 4He nuclei. In this paper, we also performed ab initio NCGSM calculations for the unstable nucleus 5He and determined the ground state energy and decay width, starting from a realistic N 3LO chiral interaction.
