Gravitation and Spacetime: Emergent from Spinor Interactions -- How?
Martin Rainer
Newtonian gravity arises as the nonrelativistic, static, weak-field limit of some Lorentzian spacetime geometry solving the generally covariant Einstein equations for a given matte…
Is Loop Quantum Gravity a QFT ?
Martin Rainer
We investigate up to which extend the kinematic setting of loop quantum gravity can be fit into a diffeomorphism invariant setting of algebraic QFT generalizing the Haag-Kastler se…
Multidimensional Sigma-Model with Black Holes and p-Branes
Martin Rainer
The bosonic content of string theory in curved background of multidimensional structure with p-branes has a systematic geometrical description as an effective sigma-model of gravit…
Algebraic Quantum Theory on Manifolds: A Haag-Kastler Setting for Quantum Geometry
Martin Rainer
Motivated by the invariance of current representations of quantum gravity under diffeomorphisms much more general than isometries, the Haag-Kastler setting is extended to manifolds…
Cones and causal structures on topological and differentiable manifolds
Martin Rainer
General definitions for causal structures on manifolds of dimension d+1>2 are presented for the topological category and for any differentiable one. Locally, these are given as con…
On the fundamental length of quantum geometry and the black hole entropy
M. Rainer
The geometric operators of area, volume, and length, depend on a fundamental length l of quantum geometry which is a priori arbitrary rather than equal to the Planck length l_P. Th…
