M.Sci. Position: Imaging Single Atoms in free space


One — two — three — many:  The ultimate limit of imaging neutral atoms in free space.  Based on our recent advances, In this project you will take imaging to its very limits using a novel fluorescence imaging technique.The work will be based in the BEC at IESL and Cretan Matter Waves groups under the supervision of Wolf von Klitzing.


The particle-wave duality is still one of the most exciting ideas of Quantum Mechanics. In recent years Bose-Einstein-Condensates (BECs) have given us for the first time access to coherent matter-waves with a large number of atoms. The conjugate of the coherent state is the Fock state, where the atom number is precisely known.  Imaging a BEC with single atom resolution would project the coherent state onto a spatially resolved Fock state, thus allowing us to study its correlation functions in great detail.

Recently, we have developed dark-ground imaging as a novel ultra-sensitive imaging technique. Based on the existing infrastructure of this project, you will test and implement a custom-made Zeiss objective, which will push the resolution limit down to little more than one micro meter. The associated increase in the photon-collection efficiency will allow us for the first time to image free single neutral atoms in situ.  Together, we will then integrate BEC1 setup, where we will look at Bose-Einstein Condensation at very low atom numbers.  The project is expected to yield one or two publications.

The successful candidate will either already be enrolled in a Master Programme (either at the University of Crete or elsewhere), or will have to apply separately to the Graduate School of the University of Crete.
