Equation of state of nuclear and neutron matter at third-order in perturbation theory from chiral EFT
J. W. Holt, N. Kaiser
We compute from chiral two- and three-nucleon interactions the energy per particle of symmetric nuclear matter and pure neutron matter at third-order in perturbation theory includi…
Lambda-nuclear interactions and hyperon puzzle in neutron stars
J. Haidenbauer, U. -G. Meißner, N. Kaiser +1
Brueckner theory is used to investigate the in-medium properties of a -hyperon in nuclear and neutron matter, based on hyperon-nucleon interactions derived within SU(3) chiral e…
Radiative corrections to the magnetic moments of the proton and the neutron
N. Kaiser
We estimate the radiative corrections of order to the magnetic moments of the proton and the neutron. The photon-loop diagram of the vertex-correction type is evaluated with…
Density-dependent effective baryon-baryon interaction from chiral three-baryon forces
Stefan Petschauer, Johann Haidenbauer, Norbert Kaiser +2
A density-dependent effective potential for the baryon-baryon interaction in the presence of the (hyper)nuclear medium is constructed, based on the leading (irreducible) three-bary…
Divergence of the isospin-asymmetry expansion of the nuclear equation of state in many-body perturbation theory
Corbinian Wellenhofer, Jeremy W. Holt, Norbert Kaiser
The isospin-asymmetry dependence of the nuclear matter equation of state obtained from microscopic chiral two- and three-body interactions in second-order many-body perturbation th…
