A coherent approach to Spacetime Foam
Remo Garattini
A coherent superposition of N Schwarzschild wormholes is proposed as a model for spacetime foam. Following the subtraction procedure for manifolds with boundaries, we calculate by…
Casimir energy and variational methods in AdS spacetime
Remo Garattini
Following the subtraction procedure for manifolds with boundaries, we calculate by variational methods, the Schwarzschild-Anti-de Sitter and the Anti-de Sitter space energy differe…
A Spacetime Foam Approach to the Schwarzschild-de Sitter Entropy
Remo Garattini
The entropy for a black hole in a de Sitter space is approached within the framework of spacetime foam. A simple model, made by wormholes in a semiclassical approximation, is t…
A Spacetime Foam approach to the cosmological constant and entropy
Remo Garattini
A simple model of spacetime foam, made by wormholes in a semiclassical approximation, is taken under examination. The Casimir-like energy of the quantum fluctuation of such a m…
Superluminal effects for quantum tunneling through two successive barriers
Vladislav S. Olkhovsky, Erasmo Recami, Giovanni Salesi
We study the phenomenon of one-dimensional non-resonant tunnelling through two successive potential barriers, separated by an intermediate free region R, by analyzing the relevant…
Localized Superluminal solutions to Maxwell equations propagating along a normal-sized waveguide
Michel Zamboni-Rached, Erasmo Recami
We show that localized (non-evanescent) solutions to Maxwell equations exist, which propagate without distortion along normal waveguides with Superluminal speed.
