A few recent activities:

• For Michigan High Schools: The 2012 Michigan Physics Olympiad will be held on May 12, 2012.

  
  

• Rydberg atoms were trapped with 90% efficiency in a pondeomotive optical lattice, and the trapping time has been mesured. For detailed results, see Phys. Rev. Lett. 107, 263001 (2011). A brief news report has been published by the University of Michigan News Service. Figure: A: Rydberg atoms prepared at the peaks of an optical lattice are mostly un-trapped, since they are able to move over the lattice wells. B: Using a lattice inversion technique, Rydberg atoms can be prepared in the lattice wells, where they are efficiently confined and trapped. (Credit: S. E. Anderson) -->

• The Rydberg excitation blockade was first seen via direct spatiual imaging. Phys. Rev. Lett. 107, 103001 (2011).
• Artificial crystals of 500nm-diameter nanoparticles trapped in an optical lattice. The nanoparticles are in a water solution and are observed using a microscope. [Phys. Rev. E 83 , 051406 (2011)].
  • Movie 1: 3D crystals of 300nm PS spheres.
  • Movie 2: 3D crystals of 190nm PS spheres. These are the smallest particles we can presently observe.
• The group operates an atom trap for the undergraduate labs. Trap movies: Low resolution [18 MByte]   -   High resolution [154 MByte]

You are invited to browse this and the Raithel Group website, to check out the research and outreach activities, and to read the posted publications. Some results are shown in the slide show below.
