A class of static spherically symmetric solutions in -gravity
Marco Calzá an Lorenzo Sebastiani
We study a class of static spherically symmetric vacuum solutions in modified teleparallel gravity solving the field equations for a specific model Ansatz, requiring the torsion sc…
First law of thermodynamics and entropy of FLRW universe in modified gravity
Lorenzo Sebastiani
We investigate the first law of thermodynamics and entropy associated to the apparent horizon of (non-flat) FLRW space-time in different theories of modified gravity and in the pre…
A class of static spherically symmetric solutions in -gravity
Marco Calzá, Lorenzo Sebastiani
We analyze a class of topological static spherically symmetric vacuum solutions in -gravity. We considered an Ansatz ensuring that those solutions trivially satisfy the field…
Some remarks on non-singular spherically symmetric space-times
Lorenzo Sebastiani, Sergio Zerbini
A short review on spherically symmetric static regular black holes and spherically symmetric non singular cosmological space-time is presented. Several models of regular black hole…
Local solutions of General Relativity in the presence of the Trace Anomaly
Marco Calzá, Alessandro Casalino, Lorenzo Sebastiani
Local solutions are a vivid and long-living topic in gravitational physics. We consider exact static pseudo-spherically symmetric solutions of semi-classical Einstein's equations i…
The Trans-Planckian Censorship Conjecture in different frameworks of viable inflation
Bruno Sanna, Lorenzo Sebastiani
We review the recently proposed Trans-Planckian Censorship Conjecture that stems from the Trans-Planckian problem of cosmological perturbations. We analyze the implications and con…
