Macroscopic mechanical systems typically respond linearly to external force, and generating nonlinearity is challenging. Here, the authors generate nonlinearity in a macroscopic mechanical resonator by linking it to a gold contact and exploiting the anharmonicity in the chemical bonding interactions.
