We discuss the phase coherence properties of a mesoscopic normal ring coupled to an electric environment via Coulomb interactions. This system can be mapped onto the Caldeira-Leggett model with a flux dependent tunneling amplitude. We show that depending on the strength of the coupling between the r
We consider a mesoscopic Josephson junction in a circular superconducting ring which encloses a magnetostatic flux. It is shown that the state of the junction can evolve in a quantum superposition of two coherent states. It is also shown that the destructive interference between these two states sup
