Description
We propose a driving scheme in dynamic Atomic Force Microscopy (AFM) to maximize the time the tip spends near the surface during each oscillation cycle. Using a quantum description of the oscillator that employs a generalized Caldeira-Leggett model for dissipative oscillator-surface interaction, we predict large classical squeezing and a small amount of skewness of the probability distribution of the oscillator. Our model also predicts that a dissipative surface force may enhance quantum effects in the motion of a micro-mechanical oscillator that interacts with a surface.
