Annihilation Signals from Asymmetric Dark Matter
Abstract:
I will begin with an overview of models of Asymmetric Dark Matter, in which the present day density of dark matter (DM) is set by a particle asymmetry, similar to baryonic matter. Annihilation-like indirect detection signals are not typically expected in the simplest models of this type, as the DM is non-self-conjugate and the relic density of anti-DM is negligible. However, for non-minimal models observable annihilation signals can occur and I will highlight some motivated models which accomplish this.

Modifications of the Nuclear Shell Structure: Spectroscopy in Islands of Inversion
Abstract:
One of the major successes in the description of the properties of atomic nuclei was the introduction of the nuclear shell model. The magic numbers associated with closed shells have long been assumed to be valid over the whole nuclear chart. In the last decades it was found that the well-known magic numbers for atomic nuclei can change locally when going from the valley of stability to nuclei with extreme N/Z ratios, leading to the disappearance of classic shell gaps and the appearance of new magic numbers.
New Textbook Wins 2013 Choice Award March 11, 2014

Mathematical modeling, statistics, and climate research are the subjects of a new textbook that recently received the 2013 ASLI Choice Award  from the Atmospheric Science Librarians International. Coauthored by Hans G. Kaper, Argonne emeritus and former director of the Mathematics and Computer Science Division, and his colleague Hans Engler, professor at Georgetown University, the textbook was selected for the annual award because of  its “accessible explanations in key areas where mathematics and climate meet.”

From Iron Pnictide Superconductors to Correlated Functional Materials by Digital Design
Abstract:
The discovery of iron pnictide high temperature superconductors in 2008 was totally unexpected and exciting. They provide us another playground to explore the mechanism of unconventional superconductivity and to test state-of-the-art electronic structure methods. However, understanding the normal state of these superconductors has proven to be challenging for both band theory and model Hamiltonian approaches.
Silicon and Germanium Detector Developments at Brookhaven
Abstract:
The talk will outline several x-ray detector developments at Brookhaven National Laboratory (BNL), including spectroscopy and position-sensing projects. Our recent advances in combining BNL-designed ASICs with monolithic segmented germanium detectors from Semikon Detectors GmBH will be described in some detail.
