Interactions between directly and parametrically driven vibration modes in a micromechanical resonator
H. J. R. Westra, D. M. Karabacak, S. H. Brongersma +3
The interactions between parametrically and directly driven vibration modes of a clamped-clamped beam resonator are studied. An integrated piezoelectric transducer is used for dire…
Q-factor control of a microcantilever by mechanical sideband excitation
W. J. Venstra, H. J. R. Westra, H. S. J. van der Zant
We demonstrate the coupling between the fundamental and second flexural mode of a microcantilever. A mechanical analogue of cavity-optomechanics is then employed, where the mechani…
Discrete-time quadrature feedback cooling of a radio-frequency mechanical resonator
M. Poot, S. Etaki, H. Yamaguchi +1
We have employed a feedback cooling scheme, which combines high-frequency mixing with digital signal processing. The frequency and damping rate of a 2 MHz micromechanical resonator…
Mechanical systems in the quantum regime
Menno Poot, Herre S. J. van der Zant
Mechanical systems are ideal candidates for studying quantumbehavior of macroscopic objects. To this end, a mechanical resonator has to be cooled to its ground state and its positi…
