A simple approach to the calculation of retarded dispersion forces
B. Carazza, R. Tedeschi
We propose a phenomenological Hamiltonian for the interaction of neutral macroscopic bodies with the electromagnetic field. Subsequently we revisit the assumption according to whic…

Decoherence within a simple Model for the Environment
B. Carazza
This article examines the decoherence of a macroscopic body using a simple model of the environment and following the evolution of the pure state for the whole system. We found tha…

On the Plasmon-like Excitations of Atomic Clusters with Application to Fullerene
B. Carazza
We present here a modified hydrodynamical model for the collective electronic excitations of spherical atomic clusters. The model is applied to the giant-dipole plasmon mode of the…
