Gauss-Bonnet dark energy by Lagrange multipliers
Salvatore Capozziello, Andrey N. Makarenko, Sergei D. Odintsov
A string-inspired effective theory of gravity, containing Gauss-Bonnet invariant interacting with a scalar field, is considered in view of obtaining cosmological dark energy soluti…
Cosmological dark energy effects from entanglement
S. Capozziello, O. Luongo, S. Mancini
The thorny issue of relating information theory to cosmology is here addressed by assuming a possible connection between quantum entanglement measures and observable universe. In p…
Hybrid f(R) theories, local constraints, and cosmic speedup
S. Capozziello, T. Harko, T. S. Koivisto +2
We present an extension of general relativity in which an term à la Palatini is added to the usual metric Einstein-Hilbert Lagrangian. Expressing the theory in a dynamically…
Bounces, turnarounds and singularities in bimetric gravity
Salvatore Capozziello, Prado Martin-Moruno
In this letter, we consider cosmological solutions of bimetric theory without assuming that only one metric is coupled to gravity. We conclude that any cosmology can be described b…
From Black Hole quantization to universal scaling laws
Salvatore Capozziello, Gerardo Cristofano, Mariafelicia De Laurentis +1
Significative developments on the primordial black hole quantization seem to indicate that the structure formation in the universe behaves under a unified scheme. This leads to the…
Wormholes supported by hybrid metric-Palatini gravity
Salvatore Capozziello, Tiberiu Harko, Tomi S. Koivisto +2
Recently, a modified theory of gravity was presented, which consists of the superposition of the metric Einstein-Hilbert Lagrangian with an term constructed à la Palati…
