Abstract :
Using an analytically solvable model of a nanoparticle interacting with a spherical optical resonator we show that particle-induced modification of the cavity mode renders standard gradient approximation for the optomechanical interaction invalid. Due to confinement, the optical force acquires a nonconservative component not related to photon scattering.
