Uniqueness of the Fock representation of the Gowdy and models
Jeronimo Cortez, Guillermo A. Mena Marugan, Jose M. Velhinho
After a suitable gauge fixing, the local gravitational degrees of freedom of the Gowdy and cosmologies are encoded in an axisymmetric field on the sphere $S^2…
Quantum Gowdy Model: Schrodinger Representation with Unitary Dynamics
Alejandro Corichi, Jeronimo Cortez, Guillermo A. Mena Marugan +1
The linearly polarized Gowdy model is paradigmatic for studying technical and conceptual issues in the quest for a quantum theory of gravity since, after a suitable and almos…
Quantum time uncertainty in Schwarzschild-anti-de Sitter black holes
Pablo Galan, Luis J. Garay, Guillermo A. Mena Marugan
The combined action of gravity and quantum mechanics gives rise to a minimum time uncertainty in the lowest order approximation of a perturbative scheme, in which quantum effects a…
High-order gauge-invariant perturbations of a spherical spacetime
David Brizuela, Jose M. Martin-Garcia, Guillermo A. Mena Marugan
We complete the formulation of a general framework for the analysis of high-order nonspherical perturbations of a four-dimensional spherical spacetime by including a gauge-invarian…
Uniqueness of the Fock quantization of the Gowdy model
Jeronimo Cortez, Guillermo A. Mena Marugan, Jose M. Velhinho
After its reduction by a gauge-fixing procedure, the family of linearly polarized Gowdy cosmologies admit a scalar field description whose evolution is governed by a Klein-Go…
Canonical Realizations of Doubly Special Relativity
Pablo Galan, Guillermo A. Mena Marugan
Doubly Special Relativity is usually formulated in momentum space, providing the explicit nonlinear action of the Lorentz transformations that incorporates the deformation of boost…
