Displacement power spectrum measurement of a macroscopic optomechanical system at thermal equilibrium

A. Di Virgilio, S. Bigotta, L. Barsotti +27

The mirror relative motion of a suspended Fabry-Perot cavity is studied in the frequency range 3-10 Hz. The experimental measurements presented in this paper, have been performed a…

Tomographic entropy and cosmology

V. I. Man'ko, G. Marmoand C. Stornaiolo

The probability representation of quantum mechanics including propagators and tomograms of quantum states of the universe and its application to quantum gravity and cosmology are r…

Gauge invariant perturbations of Scalar-Tensor Cosmologies: The vacuum case

Sante Carloni, Peter K. S. Dunsby, Claudio Rubano

The covariant gauge invariant perturbation theory of scalar cosmological perturbations is developed for a general Scalar-Tensor Friedmann-Lemaitre-Robertson-Walker cosmology in a v…

Noether symmetry approach in pure gravity with variable G and Lambda

Alfio Bonanno, Giampiero Esposito, Claudio Rubano +1

We find exact cosmological solutions when the Newton parameter and the cosmological term are dynamically evolving in a renormalization-group improved Hamiltonian approach. In our d…

Cosmological model with Born-Infeld type scalar field

Antonio Troisi, Emmanuel Sérié, Richard Kerner

The non-abelian generalization of the Born-Infeld non-linear lagrangian is extended to the non-commutative geometry of matrices on a manifold. In this case not only the usual SU(n)…

On boosted space-times with cosmological constant and their ultrarelativistic limit

Giampiero Esposito, Roberto Pettorino, Paolo Scudellaro

The problem of deriving a shock-wave geometry with cosmological constant by boosting a Schwarzschild-de Sitter (or anti-de Sitter) black hole is re-examined. Unlike previous work i…

Quantum cosmology from three different perspectives

Giampiero Esposito

Our review is devoted to three promising research lines in quantum cosmology and the physics of the early universe. The nonperturbative renormalization programme is making encourag…

Kerr black hole lensing for generic observers in the strong deflection limit

V. Bozza, F. De Luca, G. Scarpetta

We generalize our previous work on gravitational lensing by a Kerr black hole in the strong deflection limit, removing the restriction to observers on the equatorial plane. Startin…

The weakly perturbed Schwarzschild lens in the strong deflection limit

V. Bozza, M. Sereno

We investigate the strong deflection limit of gravitational lensing by a Schwarzschild black hole embedded in an external gravitational field. The study of this model, analogous to…
