Schwarzschild Field with Maximal Acceleration Corrections

A. Feoli, G. Lambiase, G. Papini +1

We consider a model in which accelerated particles experience line--elements with maximal acceleration corrections. When applied to the Schwarzschild metric, the effective field ex…

Higher-Order Corrections to the Effective Gravitational Action from Noether Symmetry Approach

S. Capozziello, G. Lambiase

Higher-order corrections of Einstein-Hilbert action of general relativity can be recovered by imposing the existence of a Noether symmetry to a class of theories of gravity where R…

Selection Rules in Minisuperspace Quantum Cosmology

S. Capozziello, G. Lambiase

The existence of a Noether symmetry for a given minisuperspace cosmological model is a sort of selection rule to recover classical behaviours in cosmic evolution since oscillatory…

New Gauge Conditions in General Relativity: What Can We Learn from Them?

Giampiero Esposito, Cosimo Stornaiolo

The construction of conformally invariant gauge conditions for Maxwell and Einstein theories on a manifold M is found to involve two basic ingredients. First, covariant derivatives…

Neutrino Oscillations in Brans-Dicke Theory of Gravity

S. Capozziello, G. Lambiase

Flavor oscillations of neutrinos are analyzed in the framework of Brans-Dicke theory of gravity. We find a shift of quantum mechanical phase of neutrino proportional to a…

New Supplementary Conditions for a Non-Linear Field Theory: General Relativity

Giampiero Esposito, Cosimo Stornaiolo

The Einstein theory of general relativity provides a peculiar example of classical field theory ruled by non-linear partial differential equations. A number of supplementary condit…

Nonminimal Derivative Couplings and Inflation in Generalized Theories of Gravity

S. Capozziello, G. Lambiase, H. -J. Schmidt

We study extended theories of gravity where nonminimal derivative couplings of the form are present in the Lagrangian. We show how and why the other coupling…

Phenomenological scaling laws relating the observed galactic dimensions to Planck action constant

Salvatore Capozziello, Salvatore De Martino, Silvio De Siena +1

It is shown that the characteristic observed radius, velocity, and temperature of a typical galaxy can be inferred from Planck action constant through a phenomenological scaling la…
