Harnessing electro-optic correlations in an efficient mechanical converter
A. P. Higginbotham, P. S. Burns, M. D. Urmey +6
An optical network of superconducting quantum bits (qubits) is an appealing platform for quantum communication and distributed quantum computing, but developing a quantum-compatibl…
Optical probing of mechanical loss of a Si_{3}N_{4} membrane below 100 mK
R. Fischer, N. S. Kampel, G. G. T. Assumpção +5
We report on low mechanical loss in a high-stress silicon nitride (Si_{3}N_{4}) membrane at temperatures below 100 mK. We isolate a membrane via a phononic shield formed within a s…
Improving broadband displacement detection with quantum correlations
N. S. Kampel, R. W. Peterson, R. Fischer +5
Interferometers enable ultrasensitive measurement in a wide array of applications from gravitational wave searches to force microscopes. The role of quantum mechanics in the metrol…
Laser cooling of a micromechanical membrane to the quantum backaction limit
R. W. Peterson, T. P. Purdy, N. S. Kampel +4
The radiation pressure of light can act to damp and cool the vibrational motion of a mechanical resonator. In understanding the quantum limits of this cooling, one must consider th…
Optomechanical Raman-Ratio Thermometry
T. P. Purdy, P. -L. Yu, N. S. Kampel +4
The temperature dependence of the asymmetry between Stokes and anti-Stokes Raman scattering can be exploited for self-calibrating, optically-based thermometry. In the context of ca…
A phononic bandgap shield for high-Q membrane microresonators
P. -L. Yu, K. Cicak, N. S. Kampel +4
A phononic crystal can control the acoustic coupling between a resonator and its support structure. We micromachine a phononic bandgap shield for high Q silicon nitride membranes a…
Strong Optomechanical Squeezing of Light
T. P. Purdy, P. -L. Yu, R. W. Peterson +2
We create squeezed light by exploiting the quantum nature of the mechanical interaction between laser light and a membrane mechanical resonator embedded in an optical cavity. The r…
The effect of light assisted collisions on matter wave coherence in superradiant Bose-Einstein condensates
N. S. Kampel, A. Griesmaier, M. P. Hornbak Steenstrup +3
We investigate experimentally the effects of light assisted collisions on the coherence between momentum states in Bose-Einstein condensates. The onset of superradiant Rayleigh sca…
