Visual observation of photonic Floquet–Bloch oscillations

Recently, the exploration of Bloch oscillations (BOs) in periodically driven quantum systems, equivalent to “Floquet systems,” has drawn tremendous attention because their exotic characteristics are profoundly distinct from those in static systems. Specifically, two types of Bloch-like oscillations have been investigated: quasi-Bloch oscillations (QBOs) and super-Bloch oscillations (SBOs).
