DB.00001: Neutrino Mass and Mixing in Astrophysics and Cosmology Invited Speaker: Astrophysical considerations may provide a probe of the properties of the mysterious neutrinos. I discuss how neutrino mass and flavor oscillations can be important in astrophysical environments like the early universe, cosmology, and core collapse supernovae. For example, supercomputer supernova simulations reveal that neutrino flavor transformation and, consequently, the expected supernova neutrino signal, can depend sensitively on the as yet unmeasured neutrino mass hierarchy and the mixing angle $\theta_{1 3}$, both targets of on-going experimental efforts. Likewise, I will argue that other aspects of neutrino physics, untestable in the laboratory, nevertheless have consequences for the physics of stellar collapse, nucleosynthesis, the early universe, and cosmology.

DB.00002: Intersections of nuclear physics and cold atom physics Invited Speaker: Cold atomic Fermi gases in which the interaction between the atoms can be tuned via Feshbach resonances are a new paradigm for strongly interacting quantum fluids. I will discuss a number of properties of these systems that are of interest to nuclear physicists: i) the equation of state, ii) superfluidity and the response to pair-breaking perturbations, iii) nearly perfect fluidity.

DB.00003: Charged Particle Radiography-a new way to look inside of things Invited Speaker: A new technique (pRad) has been developed at LANL, which uses high energy protons for flash radiography. PRad allows much more detailed information to be obtained from dynamic experiments than was ever available in the past. Since the first demonstration of the focusing of protons for radiography in 1995, huge progress has been made in developing techniques for dynamic imaging that have made proton radiography an important contributor to the study weapons physics. Approximately 40 small scale dynamic experiments are preformed per year using the line C facility at LANSCE. Movies of up to 32 frames can be made of explosively driven experiments, allowing new phenomena to be observed and quantified. New capabilities are being added to the facility continuously. Spin offs from pRad include muon tomography and proton tomography. These techniques will be described and results from recent experiments will be presented. [Preview Abstract] |
