Applied Physics Seminar
Precision Gravimetry and Magnetic Gradiometry with Ultra Cold Atoms
Abstract: In this talk, I will discuss the development of cold atom precision inertial sensors based on thermal and bose condensed atomic sources. The talk will provide an introduction to the technology and will discuss recent results from our labs at the Australian National University in terms of straightforward (but accurate) analytic models that I will develop in the talk. I will discuss developments including high flux sources, quantum non demolition squeezing and large momentum transfer beam splitting and how these techniques can be exploited to improve precision, bandwidth and SWaP for field deployed devices. I will also touch on applications from navigation, to earth science and planetary science.
Biography: Professor John Close completed his PhD in physics at the University of California, Berkeley in 1991. He was a postdoctoral fellow at the University of Washington, Seattle from 1991 to 1994 and an Alexander von Humboldt Fellow and Max Planck Fellow at the Max Planck Institüt für Strömungsforschung in Göttingen from 1994 to 1998. He returned to Australia and was awarded a Queen Elizabeth II Fellowship in 2000. Professor Close is currently Deputy Director (Education) of the Research School of Physics and Engineering.
