Response of massive bodies to gravitational waves
Ludger Hannibal, Jens Warkall
The response of a massive body to gravitational waves is described on the microscopic level. The results shed a new light on the commonly used oscillator model. It is shown that ap…
Existence of axially symmetric solutions in SU(2)-Yang-Mills and related theories
Ludger Hannibal, Carl von Ossietzky
The paper is withdrawn because the analysis appeared to be incomplete.
Singularities in axially symmetric solutions of Einstein-Yang-Mills and related theories
Ludger Hannibal
We show that the solutions of SU(2) Yang-Mills-dilation and Einstein-Yang-Mills-dilaton theories described in a sequence of papers by Kleihaus and Kunz are not regular in the gauge…
Geometric Foundation of Spin and Isospin
Ludger Hannibal
Various theories of spinning particles are interpreted as realizing elements of an underlying geometric theory. Classical particles are described by trajectories on the Poincare gr…
Neutral Kaon decay without symmetry violation: A nonstandard theoretical speculation
Ludger Hannibal
It is shown that if antiparticles are realized in quantum field theory by negative frequency states, which nevertheless have positive energy density, the resulting theory provides…
On Hegerfeldt's paradox
Ludger Hannibal
The acausal behavior of relativistic states exhibited by Hegerfeldt is shown not to be present in physical systems described by first order in time evolution equations.
