Nonreciprocal transport based on cavity Floquet modes in optomechanics
Laure Mercier de Lépinay, Caspar F. Ockeloen-Korppi, Daniel Malz +1
Directional transport is obtained in various multimode systems by driving multiple, nonreciprocally-interfering interactions between individual bosonic modes. However, systems sust…
Realization of directional amplification in a microwave optomechanical device
L. Mercier de Lépinay, E. Damskägg, C. F. Ockeloen-Korppi +1
Directional transmission or amplification of microwave signals is indispensable in various applications involving sensitive measurements. In this work we show in experiment how to…
Sideband cooling of nearly degenerate micromechanical oscillators in a multimode optomechanical system
C. F. Ockeloen-Korppi, M. F. Gely, E. Damskägg +3
Multimode optomechanical systems are an emerging platform for studying fundamental aspects of matter near the quantum ground state and are useful in sensitive sensing and measureme…
Revealing hidden quantum correlations in an electromechanical measurement
C. F. Ockeloen-Korppi, E. Damskägg, G. S. Paraoanu +2
Under a strong quantum measurement, the motion of an oscillator is disturbed by the measurement back-action, as required by the Heisenberg uncertainty principle. When a mechanical…
