Local causal structures, Hadamard states and the principle of local covariance in quantum field theory
quantum field theory local covariance
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
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...
