Decoherence of Friedmann-Robertson-Walker Geometries in the Presence of Massive Vector Fields with U(1) or SO(3) Global Symmetries
O. Bertolami, P. V. Moniz
Retrieval of classical behaviour in quantum cosmology is usually discussed in the framework of {\em midi}superspace models in the presence of scalar fields and the inhomogeneous mo…
Decoherence of Homogeneous and Isotropic Metrics in the Presence of Massive Vector Fields
O. Bertolami, P. V. Moniz
Retrieval of classical behaviour in quantum cosmology is usually discussed in the framework of minisuperspace models in the presence of scalar fields together with the inhomogeneou…
Decoherence of Homogeneous and Isotropic Geometries in the Presence of Massive Vector Fields
O. Bertolami, P. V. Moniz
Decoherence of Friedmann-Robertson-Walker (FRW) geometries due to massive vector fields with global symmetry is discussed in the context of Quantum Cosmology. (Talk present…
Quantization of a Locally Supersymmetric Friedmann Model with Supermatter
A. D. Y. Cheng, P. D. D'Eath, P. R. L. V. Moniz
The general theory of N = 1 supergravity with supermatter is studied using a canonical approach. The supersymmetry and gauge constraint generators are found. The framework is appli…
Quantization of Bianchi Models in N=1 Supergravity with a Cosmological Constant
A. D. Y. Cheng, P. D. D'Eath, P. R. L. V. Moniz
We study the quantization of some cosmological models within the theory of N=1 supergravity with a positive cosmological constant. We find, by imposing the supersymmetry and Lorent…
Quantization of the Bianchi type-IX model in supergravity with a cosmological constant
A. D. Y. Cheng, P. D. D'Eath, P. R. L. V. Moniz
Diagonal Bianchi type-IX models are studied in the quantum theory of supergravity with a cosmological constant. It is shown, by imposing the supersymmetry and Lorentz qua…
