Phys. Rev. Lett. 69, 1819–1822 (1992)Voltage-current characteristics of the two-dimensional gauge glass modelReceived 19 March 1992; published in the issue dated 21 September 1992 We study the normal-to-superconductor transition, within the two-dimensional gauge glass model, as a model of strongly disordered thin-film superconductors. The voltage-current characteristics are computed using dynamical simulation. At high temperature, we find the expected result that E∼Ja(T), with a(T)>1 for large current. It crosses over a linear resistivity at small current. Surprisingly, our results reveal a low-temperature regime in which E∼exp[-(JT/J)μ] with μ≃0.5. A possible finite-temperature glass transition is discussed. © 1992 The American Physical Society URL:
