摘要: A two-dimensional superconducting array with applied external currents is studied both analytically and numerically. With the Hamiltonian describing stationary state of system, authors calculate current-voltage characteristics and, remarkably, obtain Ohmic behaviour in low-current regime, thus providing a natural explanation anomalous observed experiments. They also present results numerical simulations Langevin equation ruling time evolution which confirm linear relation obtained analytically. Implications for dynamic KT theory are discussed.
