Casimir Energy and the Cosmological Constant
Remo Garattini
We regard the Wheeler-De Witt equation as a Sturm-Liouville problem with the cosmological constant considered as the associated eigenvalue. The used method to study such a problem…
Spacetime Foam and Vacuum Energy
Remo Garattini
A simple model of spacetime foam, made by spherically symmetric wormholes, with or without a cosmological term is proposed. The black hole area quantization and its consequences ar…
Wormholes and Spacetime Foam: an approach to the Cosmological Constant and Entropy
Remo Garattini
This paper summarizes the contribution presented at the IX Marcel Grossmann Meeting (Rome, July 2000). A simple model of spacetime foam, made by Schwarzschild wormholes in a se…
On the existence of nontrivial solutions for a nonlinear equation relative to a measure-valued Lagrangian on homogeneous spaces
Remo Garattini
We prove the existence of a non-trivial solution for a nonlinear equation related to a measure-valued Lagrangian. The result is based on a compact embedding theorem of the Lagrangi…
Spacetime Foam and the Casimir Energy
Remo Garattini
We conjecture that the neutral black hole pair production is related to the vacuum fluctuation of pure gravity via the Casimir-like energy. A generalization of this process to a mu…
Probing Vacuum with Variational Methods in Quantum Gravity
Remo Garattini
We use variational methods to calculate quasilocal energy quantum corrections. A comparison with the effective potential calculated at quadratic order is made by means of gaussian…
