Thermodynamic Gravity with Non-Extensive Horizon Entropy and Topological Calibration
Marco Figliolia, Petr Jizba, Gaetano Lambiase
We revisit Jacobson's thermodynamic derivation of gravity for generalized, non-extensive horizon entropies and develop a consistent framework in which modified gravitational dynami…
Constraining quantum fluctuations of spacetime foam from BBN
Saurya Das, Gaetano Lambiase, Elias C. Vagenas
A possibility to describe quantum gravitational fluctuations of the spacetime background is provided by virtual -branes. These effects may induce a tiny violation of the Lorentz…
PeV IceCube signals and tension in the framework of Non-Local Gravity
Salvatore Capozziello, Gaetano Lambiase
We study possible effects of non-local gravity corrections on the recent discovery by the IceCube collaboration reporting high-energy neutrino flux detected at energies of order Pe…
Modified dispersion relations and a potential explanation of the EDGES anomaly
Saurya Das, Mitja Fridman, Gaetano Lambiase +2
The Experiment to Detect the Global Epoch of Reionisation Signature (EDGES) collaboration has recently reported an important result related to the absorption signal in the Cosmic M…
Constraints on extended gravity models through gravitational wave emission
Gaetano Lambiase, Mairi Sakellariadou, Antonio Stabile
Using recent experimental results of detection of gravitational waves from the binary black hole signals by Advanced LIGO and Advanced Virgo, we investigate the propagation of grav…
The gravitino problem in Extended Gravity cosmologies
Salvatore Capozziello, Gaetano Lambiase
The gravitino problem is investigated in the framework of Extended Gravity cosmologies. In particular, we consider gravity, the most natural extension of the Hilbert-Einstei…
Neutrino pair annihilation () in the presence of quintessence surrounding a black hole
G. Lambiase, L. Mastrototaro
Quintessence fields, introduced to explain the speed-up of the Universe, might affect the geometry of spacetime surrounding black holes, as compared to the standard Schwarzschild a…
Testing fundamental physics with photon frequency shift
Luca Buoninfante, Gaetano Lambiase, Antonio Stabile
We propose a high precision satellite experiment to further test Einstein's General Relativity and constrain extended theories of gravity. We consider the frequency shift of a phot…
Consequences of Modified Cosmologies in DM abundance and PeV IceCube signals
G. Lambiase
To explain the high-energy astrophysical neutrino flux with energies recently observed by IceCube collaboration and the relic abundance of DM in the Universe, we conside…
PeV IceCube signals and Dark Matter relic abundance in modified cosmologies
G. Lambiase, S. Mohanty, A. Stabile
The discovery by the IceCube experiment of a high-energy astrophysical neutrino flux with energies of the order of PeV, has opened new scenarios in astroparticles physics. A possib…
Testing Dark energy models in the light of tension
Gaetano Lambiase, Subhendra Mohanty, Ashish Narang +1
It has been pointed out that there exists a tension in measurement between CMB and LSS observation. In this paper we show that observations can be used to test…
Casimir effect in Extended Theories of Gravity
G. Lambiase, A. Stabile, An. Stabile
We study the Casimir vacuum energy density and the Casimir pressure for a massless scalar field confined between two nearby parallel plates in a slightly curved, static spacetime b…
Astrophysical constraints on extended gravity models
Gaetano Lambiase, Mairi Sakellariadou, Antonio Stabile +1
We investigate the propagation of gravitational waves in the context of fourth order gravity nonminimally coupled to a massive scalar field. Using the damping of the orbital period…
Thermal relics in cosmology with bulk viscosity
A. Iorio, G. Lambiase
In this paper we discuss some consequences of cosmological models in which the primordial cosmic matter is described by a relativistic imperfect fluid. The latter takes into accoun…
Probing Models of Extended Gravity using Gravity Probe B and LARES experiments
S. Capozziello, G. Lambiase, M. Sakellariadou +2
We consider models of Extended Gravity and in particular, generic models containing scalar-tensor and higher-order curvature terms, as well as a model derived from noncommutative s…
Constraints on NonCommutative Spectral Action from Gravity Probe B and Torsion Balance Experiments
Gaetano Lambiase, Mairi Sakellariadou, Antonio Stabile
Noncommutative spectral geometry offers a purely geometric explanation for the standard model of strong and electroweak interactions, including a geometric explanation for the orig…
