Research output: Contribution to journalArticlepeer-review


Voltage noise in the presence of DC currents in periodic superconducting Al wire networks exhibits a striking dependence on the applied field which determines commensurability of vortices with the underlying lattice. AC currents suppress the noise. We find analogies with charge-density-wave depinning and use a relative phase-slip model to account for these effects.
