| Dielectronic recombination (DR) is an important recombination process in the high temperature and astrophysical plasmas. In this talk we will show that it is possible to identify the energetically unresolved high ι states that contribute to DR by measuring the autoionization rate as a function of electric field. We measure the autoionization yields of the excited isotropic and anisotropic cores of Ba, 6p j nl, j=1/2, 3/2, ι >10 in the electric field and determine the highest ι such that the autoionization rate is equal to the radiative rate of Ba + 6p, AR=3.88×10 -9 . |

| Physics Building | “Collider and Flavor Phenomenology in the Scalar sector of Warped Extra Dimensions” |
| I will review and present new results regarding the phenomenology of the two (presumably) lightest scalars in the context of warped extra dimensions: the Higgs and the radion. This last one, could be the lightest "new physics" state to be discovered at the LHC in this type of models. Its phenomenology is very similar to the Standard Model (SM) Higgs. When SM fields are allowed to live in the bulk of the extra dimension, new interesting effects appear in the scalar sector of the model. In particular, both the Higgs and the radion can now typically mediate Flavor Changing Neutral Currents at tree level. These will impose bounds on the flavor structure of the model, but also allow for interesting probes in current and future collider experiments. |

| Physics Building | “Spin exchange interactions and magnetic properties” |
| This talk will briefly review how the spin exchange interactions of magnetic solids are described quantitatively and qualitatively. When the choice of a spin lattice is made by inspecting the geometrical pattern of the magnetic ion arrangement or by seeking the novelty of the physics the chosen model generates, interesting but erroneous interpretations often result. The importance of choosing a spin lattice on the basis of electronic structure considerations is emphasized. The magnetic solids to be discussed in this talk include: Cs 2 CuCl 4 , Na 3 Cu 2 SbO 6 , Bi 4 Cu 3 V 2 O 14 , Cu 3 (CO 3 ) 2 (OH) 2 , AgCrO 2 , Ca 3 CoMnO 6 , MnWO 4 , [Cu(HF 2 )(pyz) 2 ]BF 4 . |

| Physics Building | “Meeting Future Energy Demand Through Unconventional Technology ” |
| Crude oil production forecasts point to a drop of 40 M b/d of conventional oil by 2030. Although the financial and economic crisis has driven global energy lower in 2009 for the first time since 1981 on any significant scale, demand will resume its long-term upward trend once the economic recovery gathers pace. By 2030, world primary energy demand is forecast to be around 45% higher than today – this is like adding two more United States to world consumption. There is therefore a drive to develop alternative energy sources as well as unconventional hydrocarbon reserves to replace the lost production from conventional reservoirs. Given that conservative estimates of Heavy Oil reserves approach 6 trillion barrels, and that heavy oil production today is approaching 10% of world production, it is reasonable to suppose that a significant percentage of the production shortfall would be filled through the production of heavy oil. These facts and the significant increase in average crude oil price since the turn of the century have led to an increased level of interest in these types of reservoirs. It is also true that due to the nature of heavy oil, while the reserves are significant, the recoverable reserves are around 5%-7%. The challenge is therefore to develop technologies that can significantly increase the recovery factors of heavy oil reservoirs in an environmentally acceptable manner. This talk will focus on the current approach adopted by industry and the technologies which will be required to address the challenges stated here. |
