David S. Weiss, Penn State University
Experiments with Atoms in One and Zero Dimensions
Physics Division Colloquium - 9 November 2007

I will review the physics of 1D Bose gases, show how we experimentally implement them, and describe experiments that confirm the longstanding exact theory across all coupling regimes. I will also describe quantum Newton's cradles, which are out-of-equilibrium 1D gases that act unlike any other many-body system, and explain what they might teach us about the nature of irreversibility in quantum systems. I will also show how, in a separate experiment, we image 3D arrays of hundreds of single atoms, an important step on the way to making a neutral atom quantum computer.
