Zero-Temperature Superconducting Transition in Frustrated Josephson-Junction Arrays
The critical behavior of zero-temperature superconducting transitions which can occur in disordered two-dimensional Josephson-junction arrays are investigated by Monte Carlo calculation of ground-state excitation energies and dynamical simulation of the current-voltage characteristics at nonzero temperatures. Two models of arrays in an applied magnetic eld are considered: random dilution of jun...
متن کاملTransition Temperature of Josephson Junction Arrays with Long-Range Interaction
We report measurements of the dependence on magnetic field and array size of the resistive transition of Josephson junction arrays with long-range interaction. Because every wire in these arrays has a large number of nearestneighbors (9 or 18 in our case), a mean-field theory should provide an excellent description of this system. Our data agree well with this mean-field calculation, which pred...
متن کاملSupersolid phase in fully frustrated Josephson junction arrays
We study the phase diagram and the excitation spectra of an array of small Josephson junctions at f = 1/2 and arbitrary charge frustration. We find that the supersolid region in the phase diagram is larger than the correspondent region at f = 0 and it includes two different phases.In the chiral supersolid (SS) charges and vortices are arranged in a checkerboard pattern on a 2 × 2 supercell anal...
متن کاملSuperconductor-insulator transition in frustrated Josephson-junction arrays on a honeycomb lattice
The zero-temperature superconductor to insulator transition is studied in a selfcharging model of Josephson-junction arrays on a honeycomb lattice in an external magnetic field corresponding to f flux quantum per plaquette. Path integral Monte Carlo simulations of the equivalent (2+1)-dimensional classical model are used to study the phase transition and critical behavior. For f = 1/3, the tran...
متن کاملTwo dynamic exponents in the resistive transition of fully frustrated Josephson-junction arrays
– We study the resistive transition in Josephson-junction arrays at f = 1/2 flux quantum per plaquette by dynamical simulations of the resistively-shunted-junction model. The current-voltage scaling and critical dynamics of the phases are found to be well described by the same critical temperature and static exponents as for the chiral (vortex-lattice) transition. Although this behavior is cons...
