Examples

1. A distinguishing feature of superconducting quantum circuits is the usage of a Josephson junction-an electrical element non existent in anharmonic oscillators.
2. As a result of the nonlinearity of anharmonic oscillators, the vibration frequency can change, depending upon the system's displacement.
3. There are many systems throughout the physical world that can be modeled as anharmonic oscillators in addition to the nonlinear mass-spring system.
4. For example, equipartition of kT / 2 does not pertain to an anharmonic oscillator that contributes quadratic and higher-order terms to the energy, right?
5. Those authors had observed long-time nearly recurrent behavior of a one-dimensional chain of anharmonic oscillators, in contrast to the rapid thermalization that had been expected.
