Extended Data Fig. 3: Frequency modulation of lattice laser.
From: Realizing discontinuous quantum phase transitions in a strongly correlated driven optical lattice
An example of the indirect sweep sequence with a final shaking frequency ff = 21 kHz and a final shaking amplitude \({{{\mathcal{A}}}}=1.9\)nm. a, b and c show variations of the modulation depth Al (the shaking amplitude \({{{\mathcal{A}}}}\)), the shaking frequency f and the laser frequency fl (the displacement of the lattice s), respectively.
