Extra-Dimensional de Broglie-Bohm Quantum Cosmology
F. A. P. Alves-Júnior, A. S. Lemos, F. A. Brito
In this work, we explore the de Broglie-Bohm Quantum Cosmology for a stiff matter, , anisotropic n-dimensional Universe. One begins by considering a Gaussian wave function f…
Hunting for extra dimensions in black hole shadows
A. S. Lemos, J. A. V. Campos, F. A. Brito
Observational data of the Sagittarius A* (Sgr A*) shadow released by the Event Horizon Telescope (EHT) are used to investigate eventual deviations in the black hole shadow radius,…
Emergence of squeezed coherent states in Kaluza-Klein cosmology
A. S. Lemos, A. S. Pereira, F. A. Brito +1
In this work, we consider a propagating scalar field on Kaluza-Klein-type cosmological background. It is shown that this geometrical description of the Universe resembles - from a…
Submillimeter constraints for non-Newtonian gravity from spectroscopy
A. S. Lemos
In this work, we consider the Yukawa-type and power-type non-Newtonian corrections, which induce amplification of gravitational interaction on submillimeter scales, and analyticall…
Spectroscopic tests for short-range modifications of Newtonian and post-Newtonian potentials
A. S. Lemos, G. C. Luna, E. Maciel +1
There are theoretical frameworks, such as the large extra dimension models, which predict the strengthening of the gravitational field in short distances. Here we obtain new empiri…
Rydberg states of hydrogen-like ions in braneworld
F. Dahia, E. Maciel, A. S. Lemos
It has been argued that precise measurements of optical transition frequencies between Rydberg states of hydrogen-like ions could be used to obtain an improved value of the Rydberg…
