    "abstract": "Nanomechanical resonators having small mass, high resonance frequency and low\ndamping rate are widely employed as mass detectors. We study the performances\nof such a detector when the resonator is driven into a region of nonlinear\noscillations. We predict theoretically that in this region the system acts as a\nphase-sensitive mechanical amplifier. This behavior can be exploited to achieve\nnoise squeezing in the output signal when homodyne detection is employed for\nreadout. We show that mass sensitivity of the device in this region may exceed\nthe upper bound imposed by thermomechanical noise upon the sensitivity when\noperating in the linear region. On the other hand, we show that the high mass\nsensitivity is accompanied by a slowing down of the response of the system to a\nchange in the mass.",
