Josephson junction chains with long-range interactions: Phase slip proliferation versus Kosterlitz-Thouless transition
Pierre Devillard 1
(14/01/2011)

The role of long range badly screened Coulomb interactions in a one-dimensional chain of Josephson junctions is studied. Correlation functions for the phase correlator are obtained as a function of the Josephson coupling energy, the short range part of Coulomb repulsion and its long range component. Though quasi-long range order is no longer possible and the usual Kosterlitz-Thouless transition no longer exists, there are remnants of it. As an application, we calculate the I
