Congratulations to Dr Philip Light and PhD Student Ashby Hilton whose research has been receiving the highest number views on the University of Adelaide Figshare. The video was also in the top 100 items viewed worldwide on institutional repositories.
The video is from their paper published in October 2018 which shows an ensemble of atoms laser cooled to around 4 millionths of a degree above absolute zero. The atoms are dropped and caught using an optical trap that confines the atoms and funnels them into a hollow core fibre. The fibre itself is 45 micro meters wide, and once inside the fibre, the atoms become an immensely ‘dark’ medium that can be used to perform quantum experiments such as the coherent storage and retrieval of optical pulses. The publication also won IPAS 2018 Best Outreach Paper Award.
IPAS researchers led by Dr Philip Light and PhD Student Ashby Hilton have created an infrared tractor beam – or light-driven energy trap – for efficiently guiding into and confining atoms inside a hollow optical fibre. The work is opening the way for new quantum experiments that may lead to new secure communications or advanced sensing technologies. This innovative research has received several interests from major media outlets such as: The Advertiser, The Lead, UK Daily Mail and was invited for the interview with ABC Radio.
High-efficiency cold-atom transport into a waveguide trap
A.P. Hilton, C. Perrella, F. Benabid, B.M. Sparkes, A.N. Luiten, and P.S. LightPhys. Rev. Applied 10, 044034 – Published 12 October 2018.
To elaborate on the IPAS’s vision and research program, Dr Ben Sparkes, who is working on quantum atom-light interactions at IPAS, was invited for an interview with Radio Adelaide’s Subatomic program with Rohan Neagle. Dr Sparkes discussed the quantum optics research taking place at IPAS and its potential to increase the distance of absolutely-secure quantum communications using our novel hollow-core optical fibres.

On Monday 27 November 2017, IPAS was delighted to host the IPAS Laser Labs tour for a group of high achieving science students from Thebarton Senior College. The students were welcomed and guided to the Quantum Atom Fibre and Sensing and Spectroscopy Labs by Dr Ben Sparkes and Sarah Scholten.The students were inspired and amazed with different demonstrations of next generation light transmission and novel gas sensing methods. All the best for our science students and looking forward to welcome you to the IPAS community in the future!
