Chiral pion-nucleon dynamics in finite nuclei: spin-isospin excitations
P. Finelli, N. Kaiser, D. Vretenar +1
The nuclear density functional framework, based on chiral dynamics and the symmetry breaking pattern of low-energy QCD, is extended to the description of collective nuclear excitat…
Dominant -exchange nucleon-nucleon interaction: Spin-spin and tensor potentials
N. Kaiser
We calculate at two-loop order in chiral perturbation theory the electromagnetic corrections to the two-pion exchange nucleon-nucleon interaction that is generated by the isovector…
Scales in nuclear matter: Chiral dynamics with pion nucleon form factors
N. Kaiser, M. Mühlbauer, W. Weise
A systematic calculation of nuclear matter is performed which includes the long-range correlations between nucleons arising from one- and two-pion exchange. Three-body effects from…
Twice-iterated boson-exchange scattering amplitudes
N. Kaiser
We calculate at two-loop order the complex-valued scattering amplitude related to the twice-iterated scalar-isovector boson-exchange between nucleons. In comparison to the once-ite…
Electromagnetic corrections to the dominant two-pion exchange nucleon-nucleon potential
N. Kaiser
We calculate at two-loop order in chiral perturbation theory the electromagnetic corrections to the dominant two-pion exchange nucleon-nucleon interaction that is generated by the…
Comment about constraints on nanometer-range modifications to gravity from low-energy neutron experiments
O. Zimmer, N. Kaiser
A topic of present interest is the application of experimentally observed quantum mechanical levels of ultra-cold neutrons in the earth's gravitational field for searching short-ra…
