(a) Current as a function of Φ for a system with N=10, with parameters
(orange, solid),
(black, dot dash) and
(blue, dash). (b) Logarithm of the ratio of the height of the 8π
and 4π
peak of the FFT of the current profile over a range of model parameters. (c) Time evolution of the some of the k-components of the momentum distribution as a function of Φ for a system with N=10, with parameters
and tR−tL=10−4tL (orange/triangles) and tR−tL=10−1tL (blue/circles). (d) Same as in c with the time window Φ[0, 8π] magnified.
