Optimizing a Dynamical Decoupling Protocol for Solid-State Electronic Spin Ensembles in Diamond

Kavli Affiliate: Viatcheslav V. Dobrovitski | First 5 Authors: Demitry Farfurnik, Andrey Jarmola, Linh M. Pham, Zhi-Hui Wang, Viatcheslav V. Dobrovitski | Summary: We demonstrate significant improvements of the spin coherence time of a dense ensemble of nitrogen-vacancy (NV) centers in diamond through optimized dynamical decoupling (DD). Cooling the sample down to $77$ K suppresses […]

Quantum dot nonlinearity through cavity-enhanced feedback with a charge memory

Kavli Affiliate: Larry Coldren | First 5 Authors: Morten P. Bakker, Thomas Ruytenberg, Wolfgang Loffler, Ajit V. Barve, Larry Coldren | Summary: In an oxide apertured quantum dot (QD) micropillar cavity-QED system, we found strong QD hysteresis effects and lineshape modifications even at very low intensities corresponding to less than 0.001 intracavity photons. We attribute […]

Serendipitous discovery of a dying Giant Radio Galaxy associated with NGC 1534, using the Murchison Widefield Array

Kavli Affiliate: Robert Goeke | First 5 Authors: Natasha Hurley-Walker, Melanie Johnston-Hollitt, Ron Ekers, Richard Hunstead, Elaine M. Sadler | Summary: Recent observations with the Murchison Widefield Array at 185~MHz have serendipitously unveiled a heretofore unknown giant and relatively nearby ($z = 0.0178$) radio galaxy associated with NGC,1534. The diffuse emission presented here is the […]

A framework for modeling the detailed optical response of thick, multiple segment, large format sensors for precision astronomy applications

Kavli Affiliate: Steven Kahn | First 5 Authors: Andrew Rasmussen, Pierre Antilogus, Pierre Astier, Chuck Claver, Peter Doherty | Summary: Near-future astronomical survey experiments, such as LSST, possess system requirements of unprecedented fidelity that span photometry, astrometry and shape transfer. Some of these requirements flow directly to the array of science imaging sensors at the […]
