The theoretical status on universal aspects of weakly-bound neutron-rich light nuclei are
reviewed, considering few-body approaches. We focus the review on the low-energy …

Effective interactions can be obtained from a renormalization group analysis in two
complementary ways. One can either explicitly integrate out higher energy modes or impose …

We present a methodology to renormalize the nucleon-nucleon interaction in momentum
space, using a recursive multiple subtraction approach that prescinds from a cutoff …

We analyze the role played by long-distance symmetries within the context of the similarity
renormalization group (SRG) approach, which is based on phase-shift-preserving …

We apply the subtracted kernel method (SKM), a renormalization approach based on
recursive multiple subtractions performed in the kernel of the scattering equation, to the …

We analyze quantitatively the interplay between explicit and implicit renormalization in
Nuclear Physics. By explicit renormalization we mean to integrate out higher energy modes …

On a finite momentum grid with N integration points pn and weights wn (n= 1,…, N) the
Similarity Renormalization Group (SRG) with a given generator G unitarily evolves an initial …

The solution of the scattering problem based on the Lippmann-Schwinger equation requires
in many cases a discretization of the spectrum in the continuum which does not respect the …

We study the infrared limit of the similarity renormalization group (SRG) using a simple toy
model for the nuclear force aiming to investigate the fixed points of the SRG evolution with …

Abstract The Similarity Renormalization Group reduces the off-shellness by driving the
evolved interaction towards a diagonal band. We analyze the infrared limit and the …
