Corrections to the optomechanical Hamiltonian from quadratic fluctuations of a moving mirror
Year: 2025
Type: erratum
Abstract: We extend the theory of the radiation pressure to include quadratic fluctuations in the position of a moving mirror. This enables the introduction of a generalized radiation pressure operator that captures higher-order effects in the mirror-field coupling. For mechanical resonators with frequencies comparable to the fundamental cavity frequency, the resulting corrections to the optomechanical Hamiltonian are quadratic in the standard radiation pressure coupling. These corrections are expected to play a significant role in the strong-coupling regime of optomechanics, electromechanics, and superconducting circuit analogs.
