Higher derivative and mimetic models on non flat FLRW space-times
Alessandro Casalino, Lorenzo Sebastiani, Luciano Vanzo +1
An effective Lagrangian approach, partly inspired by Quantum Loop Cosmology (QLC), is presented and formulated in a non flat FLRW space-times, making use of modified gravitational…
Scale-invariant inflation with one-loop quantum corrections
Silvia Vicentini, Luciano Vanzo, Massimiliano Rinaldi
We study quantum corrections to an inflationary model, which has the attractive feature of being classically scale-invariant. In this model, quadratic gravity plays along a scalar…
On a WKB formula for echoes
L. Sebastiani, L. Vanzo, S. Zerbini
We present an unified approach for the study of idealized gravitational compact objects like wormholes and horizonless stars, here simulated by the presence of boundary conditions…
Action growth for black holes in modified gravity
Lorenzo Sebastiani, Luciano Vanzo, Sergio Zerbini
The general form of the action growth for a large class of static black hole solutions in modified gravity which includes -gravity models is computed. The cases of black hole…
Inflation and reheating in theories with spontaneous scale invariance symmetry breaking
Massimiliano Rinaldi, Luciano Vanzo
We study a scale-invariant model of quadratic gravity with a non-minimally coupled scalar field. We focus on cosmological solutions and find that scale invariance is spontaneously…
Scale-invariant rotating black holes in quadratic gravity
Guido Cognola, Massimiliano Rinaldi, Luciano Vanzo
Black hole solutions in pure quadratic theories of gravity are interesting since they allow to formulate a set of scale-invariant thermodynamics laws. Recently, we have proven that…
