Bose-Einstein condensates and Rydberg atoms in optical lattices
Dr. Oliver Morsch
University of Pisa
In the last decade, ultracold atoms and Bose-Einstein condensates in optical lattices (light-induced periodic arrays) have become important tools for studying quantum phenomena and simulating solid-state systems. In parallel to this development, ultra-cold Rydberg atoms have been investigated with a view to creating strongly interacting quantum gases and, ultimately, implementing quantum logic gates. In my talk I will report on recent efforts in our group towards the combination of those two approaches: creating a spatially ordered, ultra-cold gas of strongly interacting Rydberg atoms. I will review some of our recent results on controlling Bose condensates in strongly driven optical lattices as well as presenting preliminary results on the Rydberg excitation of atoms in Bose-Einstein condensates inside harmonic and periodic dipole traps.
