Generation of ultralow power phononic combs
We demonstrate excitation of phononic frequency combs in a bulk acoustic wave system at a temperature of 20mK using a single tone low power signal source. The observed ultralow power threshold is due to a combination of a very high quality factor of 4.2×10^{8} and relatively strong nonlinear effects...
