Extended Data Figure 2: Micromotion for near-resonant driving.
From: Enhancement and sign change of magnetic correlations in a driven quantum many-body system
a, b, Nearest-neighbour spin–spin correlator C for the lattice configuration in Fig. 3 and K0 = 1.30(3), as a function of modulation time after the ramp up of the drive, sampled within one oscillation period. We observe substantial micromotion both for the case of enhanced antiferromagnetic correlations (a; U/h = 3.8(1) kHz and ω/(2π) = 3 kHz) and for ferromagnetic correlations (b; U/h = 4.4(1) kHz and ω/(2π) = 6 kHz). For a different set of parameters in the measurement of the micromotion it should be also possible to switch between antiferromagnetic and ferromagnetic correlations within one driving cycle. The open symbols represent a reference measurement in the static case with all other parameters being equal. Solid lines are sinusoidal fits to the data, which results in a fitted frequency of 
(a) or 
(b). Error bars denote the standard error of 10 independent measurements.
