Violation of Bell inequalities from Cosmic Microwave Background data
Roberto Dale, Jesús M. Gandía, Juan Antonio Morales-Lladosa +1
In a recent paper [R. Dale. R. Lapiedra, and J. A. Morales-Lladosa, Phys. Rev. D {\bf 107}, 023506 (2023)] a cosmic-like Clauser-Horne-Shimony-Holt (CHSH) inequality was proved for…
Cosmic primordial density fluctuations and Bell inequalities
Roberto Dale, Ramon Lapiedra, Juan Antonio Morales-Lladosa
The temperature measurements, , of the perturbed cosmic microwave background, performed by the cosmic background explorer satellite (COBE), are considered. A dichotomist functio…
Solutions of the Einstein field equations for a bounded and finite discontinuous source, and its generalization: Metric matching conditions and jumping effects
Ramon Lapiedra, Juan Antonio Morales-Lladosa
We consider the metrics of the General Relativity, whose energy-momentum tensor has a bounded support where it is continuous except for a finite step across the corresponding bound…
Cosmic censorship conjecture in some matching spherical collapsing metrics
Ramon Lapiedra, Juan Antonio Morales-Lladosa
A physically plausible Lema{\^ı}tre-Tolman-Bondi collapse in the marginally bound case is considered. By "physically plausible" we mean that the corresponding metric is ${\cal C}^1…
Spherical symmetric parabolic dust collapse: matching metric with zero intrinsic energy
Ramon Lapiedra, Juan Antonio Morales-Lladosa
The collapse of marginally bound, inhomogeneous, pressureless (dust) matter, in spherical symmetry, is considered. The starting point is not, in this case, the integration of the E…
Geodesic family of spherical instantons and cosmic quantum creation
Ramon Lapiedra, Juan Antonio Morales-Lladosa
The Einstein field equations for any spherically symmetric metric and a geodesic perfect fluid source are cast in a canonical simple form, both for Lorentzian metrics and for insta…
