We study internal resonances in a membrane nanoelectromechanical system, revealing a phononic frequency comb. Using a pump-noisy-probe technique and theoretical modeling, we uncover significant squeezing, bimodality, and limit cycle formation. Our findings have implications for advanced sensing technologies and novel phononic metamaterials.

We develop a Floquet expansion framework for interacting bosonic driven systems, surpassing standard approaches by addressing the quantum-classical mismatch and extending beyond the rotating wave approximation. Our method improves the accuracy of multiphoton resonance positions, crucial for qubit architecture calibration.
