Friday Afternoon Seminar
We meet every Friday at 5PM in either the Graduate Lounge (D129) or in S240.
We get our pizza from Fratelli's Italian Eatery, a fantastic New York Pizza joint, and if you have requests for specific varieties please feel free to ask.
Previous year's FAS speakers and abstracts are available here:

|September 14 2018||Axel Drees||Thermal radiation from the QGP: Research Opportunities in Heavy Ion Physics at Stony Brook||In collisions of heavy ions at high energies small droplets of quark-gluon plasma (QGP) are formed in the laboratory at the BNL and CERN accelerator facilities, recreating the state of matter of the universe until about 10 micro seconds after the big bag. My group studies of these droplets of QGP using the PHENIX experiment at BNL’s relativistic heavy ion collider RHIC. In particular, we use the thermal radiation emitted by the QGP droplets to characterize the properties of this hot and dense form of matter. My talk will give an overview of the latest research results, including a sneak preview of results that will be submitted for publication in the next weeks, and future research opportunities.|
|September 21 2018||Jennifer Cano||What are topological phases of matter?||I will first define a topological band structure, using the Chern insulator and time-reversal protected topological insulator as examples. I will then discuss the role of symmetry. Finally, I will outline the past and future research directions of my group.|
|September 28 2018||Cyrus Dreyer||Computational materials physics for next generation electronics||The next generation of electronic devices for, e.g., computing, sensing, energy production, and energy storage, require new materials to be discovered and developed, and novel phenomena to be utilized. First-principles computational calculations based on density-functional theory (DFT) play a key role in linking the concepts of condensed matter physics to the properties of real materials and the phenomena for such applications. I will give a brief introduction to DFT and how it can be used to predict and elucidate properties of electronic materials. To illustrate this, I will give examples relating to quantum processes at point defects, as well as electromechanical coupling in insulators.|
