Non-parametric reconstruction of an inflaton potential from Einstein-Cartan-Sciama-Kibble gravity with particle production
Shantanu Desai, Nikodem J. Poplawski
The coupling between spin and torsion in the Einstein-Cartan-Sciama-Kibble theory of gravity generates gravitational repulsion at very high densities, which prevents a singularity…
Thermal fluctuations in Einstein-Cartan-Sciama-Kibble-Dirac bouncing cosmology
Nikodem J. Poplawski
We study cosmological perturbations arising from thermal fluctuations in the big-bounce cosmology in the Einstein-Cartan-Sciama-Kibble theory of gravity. We show that such perturba…
Mass of the universe in a black hole
Nikodem J. Poplawski
If spacetime torsion couples to the intrinsic spin of matter according to the Einstein-Cartan-Sciama-Kibble theory of gravity, then the resulting gravitational repulsion at supranu…
Big bounce from spin and torsion
Nikodem J. Poplawski
The Einstein-Cartan-Sciama-Kibble theory of gravity naturally extends general relativity to account for the intrinsic spin of matter. Spacetime torsion, generated by spin of Dirac…
On the mass of the Universe born in a black hole
Nikodem J. Poplawski
It is shown, using the Einstein-Cartan-Sciama-Kibble theory of gravity, that gravitational collapse of spin-fluid fermionic matter with a stiff equation of state in a black hole of…
Cosmology with torsion: An alternative to cosmic inflation
Nikodem J. Poplawski
We propose a simple scenario which explains why our Universe appears spatially flat, homogeneous and isotropic. We use the Einstein-Cartan-Kibble-Sciama (ECKS) theory of gravity wh…
