Full capacitance-matrix effects in driven Josephson-junction arrays
Frank Gibbons, A. Góngora-T, Jorge V. José
We study the dynamic response to external currents of periodic arrays of Josephson junctions, in a resistively capacitively shunted junction (RCSJ) model, including full capacitanc…
Single-vortex-induced voltage steps in Josephson-junction arrays
P. H. E. Tiesinga, T. J. Hagenaars, J. E. van Himbergen +1
We have numerically and analytically studied ac+dc driven Josephson-junction arrays with a single vortex or with a single vortex-antivortex pair present. We find single-vortex step…
1/ω-flux-noise and dynamical critical properties of two-dimensional XY-models
P. H. E. Tiesinga, T. J. Hagenaars, J. E. van Himbergen +1
We have numerically studied the dynamic correlation functions in thermodynamic equilibrium of two-dimensional O(2)-symmetry models with either bond (RSJ) or site (TDGL) dissipation…
Critical properties of two-dimensional Josephson junction arrays with zero-point quantum fluctuations
Cristian Rojas, Jorge V. José
We present results from an extensive analytic and numerical study of a two-dimensional model of a square array of ultrasmall Josephson junctions. We include the ultrasmall self and…
Superconducting to normal state phase boundary in arrays of ultrasmall Josephson junctions
Jorge V. José, Cristian Rojas
We study the competition between Josephson and charging energies in two-dimensional arrays of ultrasmall Josephson junctions, when the mutual capacitance is dominant over the self-…
Non-equilibrium coherent vortex states and subharmonic giant Shapiro steps in Josephson junction arrays
Daniel Domínguez, Jorge V. José
This is a review of recent work on the dynamic response of Josephson junction arrays driven by dc and ac currents. The arrays are modeled by the resistively shunted Josephson junct…
