A generalized Hamiltonian Constraint Operator in Loop Quantum Gravity and its simplest Euclidean Matrix Elements
Marcus Gaul, Carlo Rovelli
We study a generalized version of the Hamiltonian constraint operator in nonperturbative loop quantum gravity. The generalization is based on admitting arbitrary irreducible SU(2)…
Loop Quantum Gravity and the Meaning of Diffeomorphism Invariance
Marcus Gaul, Carlo Rovelli
This series of lectures gives a simple and self-contained introduction to the non-perturbative and background independent loop approach of canonical quantum gravity. The Hilbert sp…
Superstrings and dark matter
R. Dick, N. Eschrich, M. Gaul
We point out that the spectrum and interactions of light states of the heterotic string indicate a string scale close to the GUT scale, and a mass generating scale for the gravitat…
Cosmological implications of a light dilaton
R. Dick, M. Gaul
Supersymmetric Peccei-Quinn symmetry and string theory predict a complex scalar field comprising a dilaton and an axion. These fields are massless at high energies, but it is known…
