Hyperon-nucleon interaction and baryonic contact terms in SU(3) chiral effective field theory
Stefan Petschauer
In this proceeding we summarize results for baryonic contact terms derived within SU(3) chiral effective field theory. The four-baryon contact terms, necessary for the description…
Effect of pairing correlations on nuclear low-energy structure: BCS and general Bogoliubov transformation
J. Xiang, Z. P. Li, J. M. Yao +3
Low-lying nuclear states of Sm isotopes are studied in the framework of a collective Hamiltonian based on covariant energy density functional theory. Pairing correlation are treate…

Tamara Niksic, Nenad Kralj, Tea Tutis +2
A new implementation of the finite amplitude method (FAM) for the solution of the relativistic quasiparticle random-phase approximation (RQRPA) is presented, based on the relativis…
Nuclear charge-exchange excitations in localized covariant density functional theory
H. Z. Liang, J. Meng, T. Nakatsukasa +5
The recent progress in the studies of nuclear charge-exchange excitations with localized covariant density functional theory is briefly presented, by taking the fine structure of s…
SU(3) chiral dynamics and baryon-baryon interactions
Stefan Petschauer
We calculate hyperon-nucleon and hyperon-hyperon interactions at next-to-leading order in SU(3) baryon chiral perturbation theory extending earlier work by the Bonn-Juelich group.…

The current status of the application of covariant density functional theory to microscopic description of nuclear fission with main emphasis on superheavy nuclei (SHN) is reviewed…
Nuclear landscape in covariant density functional theory
A. V. Afanasjev, S. E. Abgemava, D. Ray +1
The neutron and proton drip lines represent the limits of the nuclear landscape. While the proton drip line is measured experimentally up to rather high -values, the location of…
Parity violation in proton-proton scattering from chiral effective field theory
J. de Vries, Ulf-G. Meißner, E. Epelbaum +1
We present a calculation of the parity-violating longitudinal asymmetry in proton-proton scattering. The calculation is performed in the framework of chiral effective field theory…

Elena Litvinova, Peter Ring, Victor Tselyaev
A two-phonon version of the relativistic quasiparticle time blocking approximation introduces as a new class of many-body models for nuclear structure calculations based on the cov…
Nuclear shell structure and response toward the limits of mass, temperature and isospin
E. Litvinova, B. A. Brown, D. -L. Fang +4
We present a short overview of our recent theoretical developments aiming at the description of exotic nuclear phenomena to be reached and studied at the next-generation radioactiv…
Dense nucleonic matter and the renormalization group
Matthias Drews, Thomas Hell, Bertram Klein +1
Fluctuations are included in a chiral nucleon-meson model within the framework of the functional renormalization group. The model, with parameters fitted to reproduce the nuclear l…
Pairing strength on the nuclear size in relativistic continuum Hartree-Bogoliubov theory
Ying Chen, Peter Ring, Jie Meng
The influence of pairing correlations on the nuclear size and in particular on the formation of nuclear halos is studied in the framework of relativistic continuum Hartree-Bogoliub…
How neutron stars constrain the nuclear equation of state
Hell Thomas, Bernhard Roettgers, Wolfram Weise
Recent neutron star observations set new constraints for the equation of state of baryonic matter. A chiral effective field theory approach is used for the description of neutron-d…
