Noise Squeezing in a Nanomechanical Duffing Resonator
Noise Squeezing in a Nanomechanical Duffing Resonator
We study mechanical amplification and noise squeezing in a nonlinear nanomechanical resonator driven by an intense pump near its dynamical bifurcation point, namely, the onset of Duffing bistability. Phase sensitive amplification is achieved by a homodyne detection scheme, where the displacement detector's output, which has a correlated spectrum around the …
