Quantum Gravitational Contributions to the CMB Anisotropy Spectrum
Claus Kiefer, Manuel Kraemer
We derive the primordial power spectrum of density fluctuations in the framework of quantum cosmology. For this purpose we perform a Born-Oppenheimer approximation to the Wheeler-D…

Topology, Decoherence, and Semiclassical Gravity
C. Kiefer
We address the issue of recovering the time-dependent Schrödinger equation from quantum gravity in a natural way. To reach this aim it is necessary to understand the nonoccurrence…
