So hot off the press, our vortices evaporated! Head to the ArXiv for the preprint of our latest collaborative paper:

Our team’s achievement of extreme precision ultrasound sensing was featured in the 6 p.m. news on Channel 7. Stefan Forstner and Warwick Bowen were honoured to show Chloe-Amanda Bailey around in our lab and talk about all the ins and outs of ultrasound, and, our favourite hobbyhorse: microdisks. If you missed it, take a look here (and please excuse the mess):

You can read more in the ITnews article below, and of course in our journal publication.

We are happy to report that our group members have sustained a threefold conference marathon in Perth, consisting of our very own biannual Optomechanics Incubator, the annual workshop of our mayor support system EQUS (The Australian Research Council Centre for Engineered Quantum Systems), and the AIP 2018 Conference. In between enjoying the dry, dry Western Austrialian heat, gorgeous beaches, and quirky quokkas, our team managed to seize no less than two poster prizes. Thumbs up to Christiaan Bekker for receiving the best student poster award at the EQUS workshop, and Yasmine Sfendla at the AIP conference!

Researchers from our laboratory have proposed a magnetomechanical system that allows the control and manipulation of mechanical resonators through magnetic interaction in the ultrastrong coupling regime. This work “Quantum magnetomechanics: Towards the ultrastrong coupling regime” is published in Physical Review B. Well done guys, keep it up.

Researchers from our laboratory have developed an evanescent biosensor which enables quantum-noise-limited tracking of single biomolecules as small as 3.5 nm, at four orders of magnitude lower intensity while maintaining state-of-the-art sensitivity. Very well done Nico, Lars, Michael, Waleed and Warwick, hats off !!! “Evanescent single-molecule biosensing with quantum-limited precision.”

Our group have demonstrated the first real-time observation of the Brownian motion of superfluid films, as well as both laser cooling and amplification of the superfluid thermal motion, by leveraging the techniques of cavity optomechanics. This work published got published in Nature Physics entitled “Laser cooling and control of excitations in superfluid helium” . Very well done Glen, David, Eugene, Chris, Eoin and Warwick, keep it up!!!

Congratulations to George, Michael and Warwick for publishing their work “Nonlinear optomechanical measurement of mechanical motion” in Nature Communications. Hats off to you guys!!!
