One-Dimensional Localization of Quantum Vortices in Disordered Josephson Junction Arrays.

چکیده
The influence of disorder on the transport of quantum vortices in one-dimensional arrays of Josephson junctions was studied experimentally. The vortices localize in disordered arrays for small vortex densities resulting in a vanishing transport at low temperatures, whereas, in a periodic array, transport remains possible. For large vortex densities the mobility of vortices is maintained in the disordered samples, due to the strong vortex-vortex interactions. [S0031-9007(96)01689-4]

One-Dimensional Mott Insulator Formed by Quantum Vortices in Josephson Junction Arrays.
The quantum transport of vortices in very long and narrow arrays of small Josephson junctions has been studied experimentally. The chemical potential of the system can be changed by an external magnetic field. When the vortex density is commensurate with the one-dimensional junction lattice, the vortex mobility vanishes for a finite window of the magnetic field. The localization of the vortices...
متن کاملVortex dynamics in dilute two dimensional Josephson junction arrays
We have investigated the dynamics of vortices in a dilute two dimensional Josephson junction array where a fraction of the superconducting islands is missing. We have used the multiple trapping model to calculate the mobility of vortices and the frequency dependence of the resistance and inductance of the array.
متن کاملDynamics of Kinks and Vortices in Josephson-junction Arrays
We present an experimental as well as theoretical study of kink motion in one-dimensional arrays of Josephson junctions connected in parallel by superconducting wires. The boundaries are closed to form a ring, and the waveform and stability of an isolated circulating kink is discussed. Two one-dimensional rings can be coupled which provides an interesting and clean platform to study interaction...
متن کاملFiske modes in one-dimensional parallel Josephson-junction arrays.
Vortices play a central role in determining the static and dynamic properties of two-dimensional (20) superconductors. Artificially fabricated networks of superconducting islands weakly coupled by Josephson junctions are model systems to study the behavior of vortices. Studies of vortices in Josephson junction arrays generally neglect the magnetic fields induced by currents flowing in the array...
متن کاملQuantum Phase Transitions and Vortex Dynamics in Superconducting Networks
Josephson-junction arrays are ideal model systems to study a variety of phenomena such as phase transitions, frustration effects, vortex dynamics and chaos. In this review, we focus on the quantum dynamical properties of lowcapacitance Josephson-junction arrays. The two characteristic energy scales in these systems are the Josephson energy, associated with the tunneling of Cooper pairs between ...
