Extended Data Fig. 4: Measured band-edge population after different sweep durations for different shaking amplitudes.
From: Realizing discontinuous quantum phase transitions in a strongly correlated driven optical lattice
a and b show the final population \({{{{\mathcal{N}}}}}_{\pi }\) after direct sweeps in the forward (from a MI to a π-SF state) and backward (from a π-SF to a MI state) directions, respectively. We extract \(\partial {{{{\mathcal{N}}}}}_{\pi }/\partial \tau\) by the linear fits (solid lines). The fit results are shown in Fig. 4c,d.
