Is Minisuperspace Quantum Gravity Reliable?

چکیده
We study minisuperspace quantum cosmology for a 2+1 dimensional Ads universe and find wave function, then we extend the model to a canonically quantized field theory for quantum gravity, i.e., a midisuperspace and solve quantum constraint the wave functional of the field theory in the saddle point approximation, we find that these two approach yield in different results.

متن کاملPath integrals and instantons in quantum gravity: Minisuperspace models.
While there does not at this time exist a complete canonical theory of full 3+1 quantum gravity, there does appear to be a satisfactory canonical quantization of minisuperspace models. The method requires no ‘choice of time variable’ and preserves the systems’ explicit reparametrization invariance. In the following study, this canonical formalism is used to derive a path integral for quantum mi...
متن کاملMinisuperspace Model for Revised Canonical Quantum Gravity
We present a reformulation of the canonical quantization of gravity, as referred to the minisuperspace; the new approach is based on fixing a Gaussian (or synchronous) reference frame and then quantizing the system via the reconstruction of a suitable constraint; then the quantum dynamics is re-stated in a generic coordinates system and it becomes dependent on the lapse function. The analysis f...

The Hartle-Hawking ‘no-boundary’ state is constructed explicitely for the recently developed supersymmetric minisuperspace model with non-vanishing fermion number. Spatially homogeneous models both in gravity and in supergravity have enjoyed some popularity in recent years as a testing ground for new ideas in quantum cosmology. One such idea, which has been discussed extensively in the literatu...
