A1.00001: Creating the Primordial Quark-Gluon Plasma at the LHC Invited Speaker: John W. Harris Ultra-relativistic collisions of heavy ions at the Large Hadron Collider (LHC) and the Relativistic Heavy Ion Collider (RHIC) create an extremely hot system at temperatures (T) expected only within the first microseconds after the Big Bang.~At these temperatures (T $\sim $ 2 x 10$^{\mathrm{12}}$ K), a few hundred thousand times hotter than the sun's core, the known ``elementary'' particles cannot exist and matter ``melts'' to form a ``soup'' of quarks and gluons, called the quark-gluon plasma (QGP). This ``soup'' flows easily, with extremely low viscosity, suggesting a nearly perfect hot liquid of quarks and gluons. Furthermore, the liquid is dense, highly interacting and opaque to energetic probes (fast quarks or gluons). RHIC has been in operation for twelve years and has established an impressive set of findings. Recent results from heavy ion collisions at the LHC extend the study of the QGP to higher temperatures and harder probes, such as jets (energetic clusters of particles), particles with extremely large transverse momenta and those containing heavy quarks. I will present a motivation for physics in the field and an overview of the new LHC heavy ion results in relation to results from RHIC. [Preview Abstract] |

A1.00002: Superposition, Entanglement, and Raising Schroedinger's Cat Invited Speaker: David Wineland Precise control of quantum systems currently occupies many labs throughout the world, with recent interest focusing on quantum information. The talk will focus on quantum information experiments in the context of trapped ions, but this is only an example of similar work that is being carried out with many other AMO and condensed matter systems.

A1.00003: The Universe According to Planck Invited Speaker: Lloyd Knox Planck is the third-generation satellite aimed at measuring the cosmic microwave background, a relic of the hot big bang. Launched in May 2009 Planck has surveyed the full sky at high sensitivity, high angular resolution and with a broad range of frequencies from 30 to 857 GHz. In this talk I will present our sky maps, their statistical properties and explain how we use them to reach conclusions about the standard cosmological model and extensions to this model. We will consider consistency with other cosmological measurements, and what we can conclude by combining them with Planck. [Preview Abstract] |
