Resonant Shapiro spikes in tunneling current of fluctuation Cooper pairs.
Numerical simulation of I–V characteristics as a function of reduced temperature 
and applied dc voltage V0 for the 1D junction at temperatures above critical. Sharp linear spikes in tunneling current at resonant dc voltages 
are developed upon approaching Tc. The corresponding values of ωτGL are between 2 and 100, which illustrates a transition between the stationary and resonant regimes. Parameters used in the simulation: 
, 
, which experimentally corresponds to a junction with Tc = 10 K under microwave radiation of frequency 53 GHz and ac voltage amplitude V1 = 0.33 mV.
