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

Both theoretical and experimental studies in the past have indicated that the charge transport in doped polyacetylene is due primarily to traveling charged solitary waves along the polymer chain backbone accompanied by hopping from one chain to another. The conductivity in this model is still determ
We explore the ground states and quantum phase transitions of two-dimensional, spin S = 1/2, antiferromagnets by generalizing lattice models and duality transforms introduced by Sachdev and , Mod. Phys. Lett. B 4, 1043). The minimal model for square lattice antiferromagnets is a lattice discretizati
