The Magnus expansion and the in-medium similarity renormalization group
T. D. Morris, N. Parzuchowski, S. K. Bogner
We present an improved variant of the in-medium similarity renormalization group (IM-SRG) based on the Magnus expansion. In the new formulation, one solves flow equations for the a…

Ultraviolet extrapolations in finite oscillator bases
S. König, S. K. Bogner, R. J. Furnstahl +2
The use of finite harmonic oscillator spaces in many-body calculations introduces both infrared (IR) and ultraviolet (UV) errors. The IR effects are well approximated by imposing a…

Equivalence of model space techniques and the renormalization group for a separable model problem
S. K. Bogner, T. T. S. Kuo
Lee-Suzuki similarity transformations and Krencigowa-Kuo folded diagrams are two common methods used to derive energy independent model space effective interactions for nuclear man…
