Our latest work is out in Nat. Commun! We report the first observation of tunnelling-assisted superfluidity in bilayer 2D quantum gases - a robust platform for quantum simulation, from superconductors to QCD. Great collaboration with @unihh & @TIIuae. https://t.co/Ut5b4ozCT1

New preprint from the Rb Team. In collaboration with researchers from @unihh and @TIIuae, we have observed a double-layer superfluid phase in 2D quantum gases trapped in controllable bilayer potentials, supported by interlayer tunnel-coupling. https://t.co/EnxYXcIYB9

The @ox_ultracold AION team proposed an experimental scheme for an atom interferometer to measure fine structure constant with improved precision. The preprint is available on arXiv. https://t.co/A1MELX4mfs

New arXiv preprint available from the 2D Bose gas experiment. We demonstrate the noise interferometry technique to detect the common mode phase fluctuation of bilayer 2D Bose gases. https://t.co/o1OvQV80uD

The @OxfordPhysics & @unihh team published in @ScienceMagazine. We quench 2D Bose gases across the BKT transition and probe the relaxation dynamics with matter-wave interferometry; we found that the scaling behaviour is consistent with real-time RG theory. https://t.co/ujYe0n3poN

Matter-wave interferometry is used to monitor the dynamics of a two-dimensional Bose gas after it is split in half.

Our new paper is published in PRL in collaboration with the Mathey Group (Hamburg). We probe the local phase fluctuation in 2D Bose gases across the BKT transition using matter-wave interferometry. #atomicphysics

Over the next years we'll be pooling the talents of our amazing team of theorists and experimentalists to create a prototype detector and work out new ways of improving the sensitivity of our measurements. Follow us for more information and updates about our work!

Our paper with NYU group (Tim Byrnes), “Faraday-imaging-induced squeezing of a double-well Bose-Einstein condensate”, was published in PRA. We propose to perform measurements of BEC to produce useful correlated states, such as squeezed and cat states. https://t.co/gnQ9Kk1aDC

We examine how nondestructive measurements generate spin squeezing in an atomic Bose-Einstein condensate confined in a double-well trap. The condensate in each well is monitored using coherent light...

Check out our new preprint on arXiv in collaboration with the Mathey group from Hamburg. We use matter-wave interferometry to observe and characterise the BKT transition in a harmonically trapped quasi-2d Bose gas. https://t.co/VinumNwto9

I’m so excited that we can finally announce this! And of course most importantly, that after a couple of years of planning and putting together the grant application we can soon start the fun part and build it! 👩🏼🔧👩🏼🔬👩🏼💻
It's official - we're building a third experiment! As part of the AION consortium we'll be developing #AtomInterferometry technology to detect #DarkMatter, #GravitationalWaves and probe fundamental physics. @UKRI_News @STFC_Matters
