Similarity renormalization group for nuclear forces
Matthias Heinz
Renormalization group methods generate low-resolution Hamiltonians that are more diagonal, with reduced coupling between low- and high-energy states, and thus easier to solve. This…

Computational schemes for the Magnus expansion of the in-medium similarity renormalization group
Matthias Heinz
The in-medium similarity renormalization group (IMSRG) is a popular many-body method used for computations of nuclei. It solves the many-body Schrödinger equation through a continu…
