Observation of Bloch oscillations with a threshold

Observation of Bloch oscillations with a threshold

We demonstrate experimentally Bloch oscillations, which occur above a certain threshold value of the effective potential gradient in lattices with specially modulated coupling between the neighboring sites. We formulate the general conditions for this phenomenon, arising due to the competition betwe...
