Isotopic chains around oxygen from evolved chiral two- and three-nucleon interactions

Understand

We extend the formalism of self-consistent Green's function theory to include three-body interactions and apply it to isotopic chains around oxygen for the first time.

• The third-order algebraic diagrammatic construction [ADC(3)] equations for two-body Hamiltonians can be exploited upon defining system-dependent one- and two-body interactions coming from the three-body force, and correspondingly dropping interaction reducible diagrams.
• This goes beyond the standard normal ordering truncations recently used in ab-inito studies.
• The Koltun sum rule for the total binding energy acquires a correction due to the added three-body interaction.
