On the Classification of Reflexive Polyhedra
M. Kreuzer, H. Skarke
Reflexive polyhedra encode the combinatorial data for mirror pairs of Calabi-Yau hypersurfaces in toric varieties. We investigate the geometrical structures of circumscribed polyto…
Direct Neutron Capture for Magic-Shell Nuclei
E. Krausmann, W. Balogh, H. Oberhummer +3
In neutron capture for magic--shell nuclei the direct reaction mechanism can be important and may even dominate. As an example we investigated the reaction Ca(n,Ca…
Geometric Interpretation and Classification of Global Solutions in Generalized Dilaton Gravity
M. O. Katanaev, W. Kummer, H. Liebl
Two dimensional gravity with torsion is proved to be equivalent to special types of generalized 2d dilaton gravity. E.g. in one version, the dilaton field is shown to be expressibl…
Classical and Quantum Gravity in 1+1 Dimensions, Part II: The Universal Coverings
T. Kloesch, T. Strobl
A set of simple rules for constructing the maximal (e.g. analytic) extensions for any metric with a Killing field in an (effectively) two-dimensional spacetime is formulated. The a…
Meson-meson interactions -- from static to dynamic valence quarks
H. R. Fiebig, H. Markum, A. Mihály +3
A method for the extraction of an effective meson-meson potential from Green functions, which can be obtained from a lattice simulation, is presented. Simulations are carried out f…
Quantum Field Theory at Finite Temperature and Cosmological Perturbations
Anton K. Rebhan
It is shown how quantum field theory at finite temperature can be used to set up self-consistent and gauge invariant equations for cosmological perturbations sustained by an ultrar…
