The nanomechanical two-mode system realized in the avoided crossing of two strongly coupled nanomechanical modes is a remarkable testbed to study Landau-Zener dynamics of single or multiple passages (Stückelberg interference) through the avoided crossing. Even more it entails analogies with two level systems, and allows for state manipulation on a classical Bloch sphere by means of radio frequency pulses, and to explore the underlying decoherence processes via Rabi, Ramsey and Hahn echo measurements.
