Depletion of the nuclear Fermi sea

Understand

The short-range and tensor components of the bare nucleon-nucleon interaction induce a sizeable depletion of low momenta in the ground state of a nuclear many-body system.

• The self-consistent Green's function method within the ladder approximation provides an \textit{ab-initio} description of correlated nuclear systems that accounts properly for these effects.
• The momentum distribution predicted by this approach is analyzed in detail, with emphasis on the depletion of the lowest momentum state.
• The temperature, density, and nucleon asymmetry (isospin) dependence of the depletion of the Fermi sea is clarified.
