Evidence for structural damping in a high-stress silicon nitride nanobeam and its implications for quantum optomechanics
S. A. Fedorov, V. Sudhir, R. Schilling +3
We resolve the thermal motion of a high-stress silicon nitride nanobeam at frequencies far below its fundamental flexural resonance (3.4 MHz) using cavity-enhanced optical interfer…
Quantum correlations of light due to a room temperature mechanical oscillator for force metrology
Vivishek Sudhir, Ryan Schilling, Sergey A. Fedorov +3
The coupling of laser light to a mechanical oscillator via radiation pressure leads to the emergence of quantum mechanical correlations between the amplitude and phase quadrature o…
Appearance and disappearance of quantum correlations in measurement-based feedback control of a mechanical oscillator
Vivishek Sudhir, Dalziel J. Wilson, Ryan Schilling +5
Quantum correlations between imprecision and back-action are a hallmark of continuous linear measurements. Here we study how measurement-based feedback can be used to improve the v…
Near-field integration of a SiN nanobeam and a SiO microcavity for Heisenberg-limited displacement sensing
Ryan Schilling, Hendrik Schütz, Amir Ghadimi +3
Placing a nanomechanical object in the evanescent near-field of a high- optical microcavity gives access to strong gradient forces and quantum-noise-limited displacement readout…
A strongly-coupled -type micromechanical system
Hajime Okamoto, Ryan Schilling, Hendrik Schütz +4
We study a classical -type three-level system based on three high- micromechanical beam resonators embedded in a gradient electric field. By modulating the strength of the fi…
