- Abstract: Periodic driving can tune the quasistatic properties of quantum matter. A
well-known example is the dynamical modification of tunneling by an oscillating
electric field. Here we show experimentally that driving the phasonic degree of
freedom of a cold-atom quasicrystal can continuously tune the effective
quasi-disorder strength, reversibly toggling a localization-delocalization
quantum phase transition. Measurements agree with fit-parameter-free
theoretical predictions, and illuminate a fundamental connection between
Aubry-Andr\'e localization in one dimension and dynamic localization in the
associated two-dimensional Harper-Hofstadter model. These results open up new
experimental possibilities for dynamical coherent control of quantum phase
transitions.

We study a model of amplification of quantum transfer and making it directed which we call the quantum ratchet model.
The ratchet effect is achieved in the quantum control model with dissipation and sink, where the Hamiltonian depends on vibrations in the energy difference synchronized with transitions between energy levels.
Amplitude and frequency of the oscillating vibron together with the dephasing rate are the parameters of the quantum ratchet which determine its efficiency.
