Relativistic dispersion relation and putative metric structure in noncommutative phase-space
P. Leal, O. Bertolami
The deformation of the relativistic dispersion relation caused by noncommutative (NC) Quantum Mechanics (QM) is studied using the extended phase-space formalism. The introduction o…
Quantum cloning and teleportation fidelity in the noncommutative phase-space
P. Leal, A. E. Bernardini, O. Bertolami
The formulation of the no-cloning theorem in the framework of phase-space noncommutative (NC) quantum mechanics (QM) is examined, and its implications for the computation of quantu…
Quantum to classical transition in the Hořava-Lifshitz quantum cosmology
Alex E. Bernardini, Pedro Leal, Orfeu Bertolami
A quasi-Gaussian quantum superposition of Hořava-Lifshitz (HL) stationary states is built in order to describe the transition of the quantum cosmological problem to the related cla…
Quantum information aspects of noncommutative quantum mechanics
Orfeu Bertolami, Alex E. Bernardini, Pedro Leal
Some fundamental aspects related with the construction of Robertson-Schrödinger like uncertainty principle inequalities are reported in order to provide an overall description of q…
Collapsing Shells and Black Holes: a quantum analysis
P. Leal, A. E. Bernardini, O. Bertolami
The quantization of a spherically symmetric null shells is performed and extended to the framework of phase-space noncommutative (NC) quantum mechanics. The encountered properties…
Aspects of Phase-Space Noncommutative Quantum Mechanics
O. Bertolami, P. Leal
In this work some issues in the context of Noncommutative Quantum Mechanics (NCQM) are addressed. The main focus is on finding whether symmetries present in Quantum Mechanics still…
Fine-structure constant constraints on Bekenstein-type models
P. M. M. Leal, C. J. A. P. Martins, L. B. Ventura
Astrophysical tests of the stability of dimensionless fundamental couplings, such as the fine-structure constant , are an area of much increased recent activity, following some…
