Chiral three-nucleon forces and the evolution of correlations along the oxygen isotopic chain

Understand

The impact of three-nucleon forces (3NFs) along the oxygen chain is investigated for the spectral distribution for attachment and removal of a nucleon, spectroscopic factors and matter radii.

• We employ self-consistent Green's function (SCGF) theory which allows a comprehensive calculation of the single particle spectral function.
• For the closed subshell isotopes, $^{14}$O, $^{16}$O, $^{22}$O, $^{24}$O and $^{28}$O, we perform calculations with the Dyson-ADC(3) method.
• The remaining open shell isotopes are studied using the newly developed Gorkov-SCGF formalism up to second order.
