Figure 5: Time-averaged physical current after a dynamical ramp with =80.

We show results for systems with filling factors: ν=0.46, 0.5 and 0.54. The red colour indicates a current flowing from sublattice to along the nearest-neighbour vectors δ_i: , δ₃=a(−1, 0). The blue colour indicates the opposite direction. The black arrows indicate the direction of the edge current and are a guide to the eye. (a) For an initial filling ν=0.46, the non-equilibrium current is concentrated along the edges and moves anticlockwise. (c) For an initial filling ν=0.54, the non-equilibrium current is concentrated along the edges and moves clockwise. (b) At half filling, both chiralities are presents. On the top and left edge the current moves clockwise, while on the bottom and right edge it moves anticlockwise. These edge currents are balanced by a current diffusing through the bulk. The non-equilibrium wavefunctions corresponding to a and c are topologically trivial (Bott index is zero) while the one corresponding to b is topological non-trivial (Bott index is one).
