Nanomechanical resonator arrays constitute a promising platform for topological physics and integrated acoustic devices. However, achieving precise control of the couplings between resonators has been a significant challenge for realizing a time-dependent Hamiltonian. In this work, we address this challenge by designing the geometric parameters of the resonators, enabling us to achieve dynamical control over the coupling strength and frequency stability.
