英文摘要:
We present the realization of a Stuckelberg interferometer with two mechanical modes in a two-coupled-cantilever-based optomechanical system. By optically tuning the frequency of one cantilever inside a cavity, we show that nonadiabatic crossing of the mechanical modes twice creates the interference fringes of the mechanical oscillations as a result of coherent splitting and subsequent recombination of the oscillations. By measuring the nonadiabatic phase acquired at the transition, we unveil an in-depth analog between the two-mode and quantum two-level systems. With this interferometry-based technique, transferring of oscillation between spatially separated cantilevers is achieved with 97% efficiency.
