Kerr spacetime in Lemaître coordinates
Francesco Sorge
We present a novel formulation of the Kerr spacetime solution, based on the Lemaître coordinates. Such an approach allows one to avoid the coordinate singularities of the Boyer-Lin…
Quasi-local Casimir energy and vacuum buoyancy in a weak gravitational field
Francesco Sorge
Casimir energy in presence of a weak gravitational field is discussed taking into account the issues related to energy and its conservation in a curved background. It is well-known…
Einstein, Planck and Vera Rubin: relevant encounters between the Cosmological and the Quantum Worlds
Paolo Salucci, Giampiero Esposito, Gaetano Lambiase +38
In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive substance that we call Dark Matter is hidden in the Universe and what is it made of?, th…
Casimir effect in free-fall towards a Schwarzschild black hole
Francesco Sorge, Justin H. Wilson
In this paper we discuss the Casimir effect in a small cavity, freely falling from spatial infinity in spacetime geometry outside of a Schwarzschild black hole. Our main goal is to…
Casimir Effect and Free Fall in a Schwarzschild Black Hole
Francesco Sorge
Scalar field vacuum energy and particle creation in a 3D Casimir apparatus, freely falling in the Schwarzschild spacetime, are considered in the reference frame of a comoving obser…
