Iterated and irreducible pion-photon exchange in nuclei
N. Kaiser
We calculate the contribution to the nuclear energy density functional which arises from iterated pion-photon exchange between nucleons. In heavy nuclei, this novel charge symmetry…
Nuclear energy density functional from chiral pion-nucleon dynamics: Isovector spin-orbit terms
N. Kaiser
We extend a recent calculation of the nuclear energy density functional in the systematic framework of chiral perturbation theory by computing the isovector spin-orbit terms: $(\ve…
Three-body spin-orbit forces from chiral two-pion exchange
N. Kaiser
Using chiral perturbation theory, we calculate the density-dependent spin-orbit coupling generated by the two-pion exchange three-nucleon interaction involving virtual -isobar e…
Chiral approach to nuclear matter: Role of explicit short-range NN-terms
S. Fritsch, N. Kaiser
We extend a recent chiral approach to nuclear matter by including the most general (momentum-independent) NN-contact interaction. Iterating this two-parameter contact-vertex with i…
Exploring the nucleus in the context of low-energy QCD
Dario Vretenar, Wolfram Weise
These lecture notes address a central problem of theoretical nuclear physics: how to establish a relationship between low-energy, non-perturbative QCD and nuclear phenomenology whi…
Dilepton emission rates from hot hadronic matter
Thorsten Renk, Amruta Mishra
The vacuum polarisation effects from the nucleon sector lead to large medium modifications of the vector meson masses in the Walecka model. With a quantum hadrodynamic framework in…
Spin-Isospin Resonances and Neutron Skin of Nuclei
D. Vretenar, N. Paar, T. Niksic +1
The Gamow-Teller resonances (GTR) and isobaric analog states (IAS) of a sequence of even-even Sn target nuclei are calculated by using the framework of the relativistic Hartree-Bog…
Spin Polarizabilities of the Nucleon from Polarized Low Energy Compton Scattering
Robert P. Hildebrandt, Harald W. Griesshammer, Thomas R. Hemmert
As guideline for forthcoming experiments, we present predictions from Chiral Effective Field Theory for polarized cross sections in low energy Compton scattering for photon energie…
Signatures of Chiral Dynamics in Low Energy Compton Scattering off the Nucleon
Robert P. Hildebrandt, Harald W. Griesshammer, Thomas R. Hemmert +1
We present a projector formalism which allows to define dynamical polarizabilities of the nucleon from a multipole expansion of the nucleon Compton amplitudes. We give predictions…
Chaos and rotational damping in particle-rotor model
Javid A. Sheikh, Yang Sun
The onset of chaos and the mechanism of rotational damping are studied in an exactly soluble particle-rotor model. It is shown that the degree of chaoticity as inferred from the st…
Relativistic nuclear model with point-couplings constrained by QCD and chiral symmetry
P. Finelli, N. Kaiser, D. Vretenar +1
We derive a microscopic relativistic point-coupling model of nuclear many-body dynamics constrained by in-medium QCD sum rules and chiral symmetry. The effective Lagrangian is char…
Chiral Dynamics in Nuclear Systems
Wolfram Weise
A survey is given on selected topics concerning the role of spontaneous chiral symmetry breaking in low-energy QCD, and its dynamical implications for nuclear systems. This include…
Kinetic description of charmonium production in high-energy nuclear collisions
Alberto Polleri, Thorsten Renk, Roland Schneider +1
We study the evolution of charmonia as they collide with the constituents of the fireball produced in high-energy nucleus-nucleus collisions. The latter evolves in a manner control…
Mean first passage time for fission potentials having structure
H. Hofmann, A. G. Magner
A schematic model of over-damped motion is presented which permits one to calculate the mean first passage time for nuclear fission. Its asymptotic value may exceed considerably th…
Spin symmetry in the anti-nucleon spectrum
Shan-Gui Zhou, Jie Meng, P. Ring
We discuss spin and pseudo-spin symmetry in the spectrum of single nucleons and single anti-nucleons in a nucleus. As an example we use relativistic mean field theory to investigat…
A note on the time evolution of the fission decay width under the influence of dissipation
H. Hofmann
The claim put forward in a recent paper by B. Jurado, K.-H. Schmidt and J. Benlliure that the transient effect of nuclear fission may be described simply as a relaxation process in…
Bound state kinetics in high-energy nuclear collisions
Alberto Polleri
A Lorentz covariant kinetic equation for bound states and their constituents is presented and solved exactly in closed form. It describes in a unified way dynamical formation and d…
Spherical Relativistic Hartree theory in a Woods-Saxon basis
Shan-Gui Zhou, Jie Meng, Peter Ring
The Woods-Saxon basis has been suggested to replace the widely used harmonic oscillator basis for solving the relativistic mean field (RMF) theory in order to generalize it to stud…
Influence of microscopic transport coefficients on the formation probabilities for super-heavy elements
Christian Rummel, Helmut Hofmann
The formation probability is shown to increase by a few orders of magnitude if microscopic transport coefficients are used rather than those of the common macroscopic pictures. Qua…
Spectral functions of isoscalar scalar and isovector electromagnetic form factors of the nucleon at two-loop order
N. Kaiser
We calculate the imaginary parts of the isoscalar scalar and isovector electromagnetic form factors of the nucleon up to two-loop order in chiral perturbation theory. Particular at…
A microscopic estimate of the nuclear matter compressibility and symmetry energy in relativistic mean-field models
D. Vretenar, T. Niksic, P. Ring
The relativistic mean-field plus RPA calculations, based on effective Lagrangians with density-dependent meson-nucleon vertex functions, are employed in a microscopic analysis of t…
Mean first passage time for nuclear fission and the emission of light particles
H. Hofmann, F. A. Ivanyuk
The concept of a mean first passage time is used to study the time lapse over which a fissioning system may emit light particles. The influence of the "transient" and "saddle to sc…
