Fermionic origin of dark energy in the inflationary universe from Unified Spinor Fields
Marcos Ramiro Alfredo Arcodía, Mauricio Bellini
In this work we explore the boundary conditions in the Einstein-Hilbert action, by considering a displacement from the Riemannian manifold to an extended one. The latter is charact…
The Heisenberg spinor field classification and its interplay with the Lounesto's classification
Marcos R. A. Arcodía, Mauricio Bellini, Roldao da Rocha
Dirac linear spinor fields were obtained from non-linear Heisenberg spinors, in the literature. Here we extend that idea by considering not only Dirac spinor fields but spinor fiel…
Particle-antiparticle duality from an extra time-like dimension
Marcos R. A. Arcodía, Mauricio Bellini
It is a well known fact that the usual complex structure on the real Clifford Algebra (CA) of Minkowski spacetime can be obtained by adding an extra time-like dimension, instead of…
Inflationary gravitational waves from unified spinor fields
Luis Santiago Ridao, Marcos Ramiro Alfredo Arcodíia, Jesús Martín Romero +1
Recent observations of Gravitational Waves (GW) generated by black-hole collisions have opened a new window to explore the universe in diverse scales. Detection of primordial gravi…
Gravitons emission during pre-inflation from unified spinor fields
Luis Santiago Ridao, Marcos Ramiro Alfredo Arcodía, Mauricio Bellini
We obtain the equation that describe the conditions of quantization for neutral massless bosons on an arbitrary curved space-time, obtained using a particular theoretical formalism…
Absorption of charged particles in a Reissner-Nordström Black-Hole: entropy evolution from Relativistic Quantum Geometry
Marcos R. A. Arcodía, Luis Santiago Ridao, Mauricio Bellini
Using Relativistic Quantum Geometry we show that the entropy can decrease in very small BHs, under certain circumstances, but always increases in very massive Black-Holes.
Geometric back-reaction in pre-inflation from relativistic quantum geometry
Marcos R. A. Arcodía, Mauricio Bellini
The pre-inflationary evolution of the universe describes the beginning of the expansion from a static initial state, such that the Hubble parameter is initially zero, but increases…
