18.01.2022 How to build and characterise a diode laser. http://www.jove.com//construction-characterization-externa

14.01.2022 Usually the signal in an interferometer to measure accelerations is limited to going up as the square of the time you look at it for. We showed that we can make the signal in our interferometer go up as the cube of the time you look at it for, or even faster. The official one: http://iopscience.iop.org/0295-5075/105/6/63001/article The free one: http://arxiv.org/abs/1311.2143

14.01.2022 We recently used machine learning to run our experiment. It did quite well! See all the details in our latest paper: http://www.nature.com/articles/srep25890 #machinelearning #ai #skynet

12.01.2022 Our latest paper. We put a soliton into an interferometer and it improves the visibility of the interference fringe. http://dx.doi.org/10.1103/PhysRevLett.113.013002

10.01.2022 Our latest publication in Physics Review A. We demonstrate phase sensitivity in a horizontally guided, acceleration-sensitive atom interferometer with a momentum separation of 80 photon recoils between its arms. A fringe visibility of 7% is observed. Our coherent pulse sequence accelerates the cold cloud in an optical waveguide, an inherently scalable route to large momentum separation and high sensitivity. We maintain coherence at high momentum separation due to both the tra...nsverse confinement provided by the guide and our use of optical delta-kick cooling on our cold-atom cloud. We also construct a horizontal interferometric gradiometer to measure the longitudinal curvature of our optical waveguide. http://pra.aps.org/abstract/PRA/v88/i5/e053620 ArXiv pre-print available at http://arxiv.org/abs/1307.0268

09.01.2022 We investigated what happens to the signal in our measurement device (an interferometer) when we change the temperature of our test masses (atoms). The official one: http://journals.aps.org//abstra/10.1103/PhysRevA.89.023626 And the free one: http://arxiv.org/abs/1312.0675

04.01.2022 A new design for a flexible laser for atom-optics applications. The official paper: http://dx.doi.org/10.1364/OE.22.010642 The free version: http://atomlaser.anu.edu.au/publicat/ecdlpapersubmitted.pdf

03.01.2022 Here you can find our recent paper! Very proud of that work, Editors' pick https://www.osapublishing.org/ol/abstract.cfm

03.01.2022 So much buzz around Michael and Joe's new paper! It even made it into Fox news among others.. http://www.foxnews.com//scientists-measure-universe-colde/,... Here are the others... http://www.abc.net.au/science/articles/2013//28/3900284.htm http://www.huffingtonpost.com//bose-einstein-condensate-co http://phys.org/ne/2013-11-physicists-coldest-universe.html http://www.livescience.com/41586-seeing-bose-einstein-conde Or, if you want to read the actual article itself... http://iopscience.iop.org/1367-2630/15/11/113060/article
