Local causal structures, Hadamard states and the principle of local covariance in quantum field theory
quantum field theory local covariance
font style='font-size:12px;'>
2010/3/18
In the framework of the algebraic formulation, we discuss and analyse some new features of the local structure of a real scalar quantum field theory in a strongly causal spacetime. In particular we us...
Quantum field theory, gravity and cosmology in a fractal universe
Fractal spacetime Models of Quantum Gravity Cosmology of Theories beyond the SM
font style='font-size:12px;'>
2010/3/18
We propose a model for a power-counting renormalizable field theory living in a fractal spacetime. The action is Lorentz covariant and equipped with a Stieltjes measure. The system flows, even in a cl...

2010/3/17
Black hole spacetimes that are topological geons in the sense of Sorkin can be constructed by taking a quotient of a stationary black hole that has a bifurcate Killing horizon. We discuss the geometri...

In the Forschungszentrum Karlsruhe an experiment has been constructed which demonstrates a homogeneous dynamo as is expected to exist in the Earth's interior. This experiment is discussed within the f...
Turning the resistive MHD into a stochastic field theory
resistive MHD stochastic field theory

Classical systems stirred by random forces of given statistics may be described via a path integral formulation in which their degrees of freedom are stochastic variables themselves, undergoing a mult...
Properties and structure of N=Z nuclei within relativistic mean field theory
mean field theory BCS approximation binding energy
font style='font-size:12px;'>
2009/9/17
The axially deformed relativistic mean field theory with the force NLSH has been performed in the blocked BCS approximation to investigate the properties and structure of N=Z nuclei from Z=20 to Z=48....
A systematic study of the superdeformation of Pb isotopes with relativistic mean field theory
Pb isotopes superdeformation relativistic mean field theory
font style='font-size:12px;'>
2009/8/17
The microscopically constrained relativistic mean field theory is used to investigate the superdeformation for Pb isotopes. The calculations have been performed with the four different interactions NL...
Topological approach to examine the singularity of the axial-vector current in an Abelian gauge field theory (QED)
axial-vector current Ward-Takahashi identity anomaly Atiyah-Singer index theorem
font style='font-size:12px;'>
2009/8/13
A topological way to distinguish divergences of the Abelian axial-vector current in quantum field theory is proposed. By using the properties of the Atiyah-Singer index theorem, the non-trivial Jacobi...
