Singularity avoidance in quantum-inspired inhomogeneous dust collapse
Yue Liu, Daniele Malafarina, Leonardo Modesto +1
In a previous paper, some of us studied general relativistic homogeneous gravitational collapses for dust and radiation, in which the density profile was replaced by an effective d…
Can static regular black holes form from gravitational collapse?
Yiyang Zhang, Yiwei Zhu, Leonardo Modesto +1
Starting from the Oppenheimer-Snyder model, we know how in classical general relativity the gravitational collapse of matter form a black hole with a central spacetime singularity.…
Fermi-bounce Cosmology and scale invariant power-spectrum
Stephon Alexander, Cosimo Bambi, Antonino Marciano +1
We develop a non-singular bouncing cosmology using a non-trivial coupling of general relativity to fermionic fields. The usual Big Bang singularity is avoided thanks to a negative…
Singularity avoidance in classical gravity from four-fermion interaction
Cosimo Bambi, Daniele Malafarina, Antonino Marciano +1
We derive the dynamics of the gravitational collapse of a homogeneous and spherically symmetric cloud in a classical set-up endowed with a topological sector of gravity and a non-m…
