Abstract
We report the measurement of average response of micromechanical resonators to very small driving forces, with a corresponding energy resolution of th e order of h omega(0), the energy quantum of the classical resonator system . The measured coherent excitation is more than an order of magnitude weake r than the random thermal fluctuations. (C) 2000 Elsevier Science B.V. All rights reserved.
