Short-range correlations in nuclei with similarity renormalization group transformations

Understand

$\mathbf{Background:}$ Realistic nucleon-nucleon interactions induce short-range correlations in nuclei.

• To solve the many-body problem unitary transformations like the similarity renormalization group (SRG) are often used to soften the interactions.
• $\mathbf{Purpose:}$ Two-body densities can be used to illustrate how the SRG eliminates short-range correlations in the wave function.
• The short-range information can however be recovered by transforming the density operators.
