Violation of the PT-symmetry and structure formation in the dark matter-gravitational wave interaction
Catarina Bastos, Hugo Terças
In flat spacetime, quantum fluctuations in dark matter, as described as a Bose-Einstein condensate, are stable and display a relativistic Bogoliubov dispersion relation. In the wea…
Entangled States and the Gravitational Quantum Well
Rui Alves, Catarina Bastos, Orfeu Bertolami
We study the continuous variable entanglement of a system of two particles under the influence of Earth's gravitational field. We determine a phase-space description of this bipart…
Vacuum decay in an interacting multiverse
S. Robles-Pérez, A. Alonso-Serrano, C. Bastos +1
We examine a new multiverse scenario in which the component universes interact. We focus our attention to the process of "true" vacuum nucleation in the false vacuum within one sin…
Bell operator and Gaussian squeezed states in noncommutative quantum mechanics
Catarina Bastos, Alex E. Bernardini, Orfeu Bertolami +2
One examines putative corrections to the Bell operator due to the noncommutativity in the phase-space. Starting from a Gaussian squeezed envelop whose time evolution is driven by c…
Phase-space noncommutative extension of the Robertson-Schroedinger formulation of Ozawa's uncertainty principle
Catarina Bastos, Alex E. Bernardini, Orfeu Bertolami +2
We revisit Ozawa's uncertainty principle (OUP) in the framework of noncommutative (NC) quantum mechanics. We derive a matrix version of OUP accommodating any NC structure in the ph…
Probing phase-space noncommutativity through quantum mechanics and thermodynamics of free particles and quantum rotors
Catarina Bastos, Alex E. Bernardini, Jonas F. G. Santos
Novel quantization properties related to the state vectors and the energy spectrum of a two-dimensional system of free particles are obtained in the framework of noncommutative (NC…
