Implementing chiral three-body forces in terms of medium-dependent two-body forces

Jeremy W. Holt, Mamiya Kawaguchi, Norbert Kaiser

Three-nucleon (3N) forces are an indispensable ingredient for accurate few-body and many-body nuclear structure and reaction theory calculations. While the direct implementation of…

Correlation Function from High-Energy Nuclear Collisions and Chiral SU(3) Dynamics

Yuki Kamiya, Tetsuo Hyodo, Kenji Morita +2

The two-particle momentum correlation function of a K^-p pair from high-energy nuclear collisions is evaluated in the KbarN-piSigma-piLambda coupled-channels framework. The effects…

Parametric correlations in energy density functionals

A. Taninah, S. E. Agbemava, A. V. Afanasjev +1

Parametric correlations are studied in several classes of covariant density functional theories (CDFTs) using a statistical analysis in a large parameter hyperspace. In the present…

Possible chiral doublets in Ni

J. Peng, Q. B. Chen

The open problem on whether or not the chirality exists in doublet bands M1 and M4 in light-mass even-even nucleus Ni is studied by adopting the recently developed fully qua…

Towards an ab initio covariant density functional for nuclear structure

Shihang Shen, Haozhao Liang, Wen Hui Long +2

Nuclear structure models built from phenomenological mean fields, the effective nucleon-nucleon interactions (or Lagrangians), and the realistic bare nucleon-nucleon interactions a…

Symmetry restoration in mean-field approaches

J. A. Sheikh, J. Dobaczewski, P. Ring +2

The mean-field approximation based on effective interactions or density functionals plays a pivotal role in the description of finite quantum many-body systems that are too large t…
