Professor Kai Bongs leads the Midlands Ultracold Atom Research Centre at the University of Birmingham. He is working in the field of cold atom quantum sensors and quantum gas mixtures.
He coordinates a collaborative European Project “iSense” with nine partners with the aim to realise a portable atom interferometric gravity sensor. He also coordinates the EPSRC Cross Disciplinary Technology programme GG-TOP, which spans across the disciplines of Physics, Civil and Electrical Engineering and Archaeology. The aim of this programme is the development of a complete portfolio of gravity gradient sensing technology – from the sensor to the 3D visualization. The focus is on applications in underground mapping from urban areas (infrastructure detection) to rural areas (archaeological artefacts).
He is PI on an EPSRC grant to realize a cold atom quantum simulator, targeting disorder phenomena such as Anderson localization and Bose glasses.
He further participates in the European project Space Optical Clock-II and the QUANTUS (quantum gases in microgravity) project funded by the German Space Agency.
He is the UK representative for the ESA m-class mission candidate STE-QUEST and serves on the ESA science team for this mission.
His work has been disseminated through both invited and peer-reviewed presentations at international conferences and through high-impact publications with over 56 publications in total. His work has been cited over 2000 times and he has an h-index of 21. His publications include one Science, one Nature Physics, 16 Physical Review Letters and one Report on Progress in Physics.
