Nuclear astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the chemical elements. This white paper summarizes progress and status of

A Detailed Examination of Astrophysical Constraints on the Symmetry Energy and the Neutron Skin of 208Pb with Minimal Modeling Assumptions

Autor: Essick, Reed, Landry, Philippe, Schwenk, Achim, Tews, Ingo

Publikováno v: Physical Review C

The symmetry energy and its density dependence are pivotal for many nuclear physics and astrophysics applications, as they determine properties ranging from the neutron-skin thickness of nuclei to the crust thickness and the radius of neutron stars.

Importance truncation for the in-medium similarity renormalization group

Autor: J. Hoppe, A. Tichai, M. Heinz, K. Hebeler, A. Schwenk

Publikováno v: Physical Review C

Ab initio nuclear many-body frameworks require extensive computational resources, especially when targeting heavier nuclei. Importance-truncation (IT) techniques allow to significantly reduce the dimensionality of the problem by neglecting unimportan

Nuclear Structure at the Crossroads

Autor: Hans Werner Hammer, Achim Schwenk, Richard Furnstahl

Publikováno v: Few Body Syst. 62, 72 (2021)

Steven Weinberg's seminal papers from 1990-92 initiated the use of effective field theories (EFTs) for nuclei. We summarize progress, priorities, and open questions for nuclear EFT developments based on the 2019 INT program "Nuclear Structure at the

In-medium similarity renormalization group with three-body operators

Autor: J. Hoppe, A. Tichai, Kai Hebeler, M. Heinz, Achim Schwenk

Publikováno v: Physical Review C

Over the past decade the in-medium similarity renormalization group (IMSRG) approach has proven to be a powerful and versatile ab initio many-body method for studying medium-mass nuclei. So far, the IMSRG was limited to the approximation in which onl
