 Dr. Jeffrey McGuirk (NIST/JILA - University of Colorado)Coherence and Correlations in an Ultra-cold Bose GasAbstract: Ultra-cold, magnetically-trapped Bose gases have great promise in a wide variety of applications ranging from fundamental studies of Bose-Einstein condensation, to quantum information, to precision measurements and fundamental tests of physics on short distance scales. Many of these applications rely on the coherence properties of Bose-Einstein condensates. I will present results of studies of coherence and correlations both above and below the degeneracy point. These results include striking macroscopic collective behavior above the degeneracy threshold (spin waves) and a surprising decrease of coherence below the onset of degeneracy (quasi-condensate modes).

 David Gepner   [email] (UIUC)Introduction to motivic stable homotopy theory, IVAbstract: We continue to explain what stable homotopy theory in topology is and how it manifests itself in Voevodsky's homotopy theory for smooth varieties. We'll keep the technical prerequisites to a minimum and we welcome interested beginners.

 Eric Landquist, (UIUC Math)So you want to Design a Factoring Algorithm? Abstract: It could mean fame, money, and perhaps even an article on Slashdot. That's right, a newer, faster factoring algorithm to crack RSA keys, contribute to the Cunningham Project, and impress your friends. This talk will first explore current factoring algorithms to see why they run at the speeds they do. Based off this information, we will look at ways to possibly speed up these algorithms or create new algorithms to run faster. Several ideas will be presented, with the goal of the talk being to promote dialogue and research into creating better factoring algorithms. No football predictions will be made, but the Curse of the Bambino may be involved.
