In our latest article, Lars Madsen,
Catxere Casacio, Alex Terrasson, Warwick Bowen and collaborators measure the viscosity of a particle within twenty microseconds and extreme precision—up to the point where the remnant uncertainty stems from its thermal molecular collisions. Read on in Nature Photonics!

Yasmine Sfendla, Chris Baker, Glen Harris, Ray Harrison, Warwick Bowen and collaborating professor Lin Tian from UC Merced have set a step towards developing the elusive all-mechanical qubit. All you need is some superfluid and a slab of silicon! Get the recipe at npj Quantum Information.
Superfluid wave trapped in a phononic crystal (or “acoustic metamaterial”). From: Sfendla, Yasmine L., et al. Extreme quantum nonlinearity in superfluid thin-film surface waves. npj Quantum Inf 7, 62 (2021)
Christopher Baker and Warwick Bowen are kicking us off for 2021 with their demonstration of broad wavelength tuning of photoluminescence on a silicon chip. Get on our wavelength at Physical Review Applied.
