Michelson Postdoctoral Prize – May 2 – May 6, 2011

The Michelson Postdoctoral Prize winner for 2011 is Lindley Winslow, a postdoctoral fellow at MIT working on the Double Chooz reactor neutrino experiment. Prior to that she worked on the KamLand reactor neutrino experiment as a graduate student at UC Berkeley where she obtained her PhD in 2008. Lindley has proposed an innovative particle detector based on quantum dots that is currently in development and that may be used to look for neutrinoless double beta decay. She is a founding member on DAEDALUS, a new experiment that aims to look for CP violation in the neutrino sector.
The Michelson Postdoctoral Prize lectures are a highlight of our academic events calendar. This year promises to be no exception.

Faculty and Staff – Learn about the GRE revised general test

Faculty, program directors and staff are invited to learn more about the GRE revised general test, which will launch later this year. The GRE and TOEFL iBT Seminar will take place April 12th from 10 to 11:30am or 1 to 2:30pm in Nord Hall 310. Topics covered will include the revised test, the TOEFL test difference and new developments, and comparing TOEFL iBT and IELTS test scores. To attend, register online. Contact Susan Benedict with questions.

Thick-wall tunneling in a piecewise linear and quadratic potential
After reviewing the basics of Coleman deLuccia tunneling, especially in the thin-wall limit, I discuss an (almost) exact tunneling solution in a piecewise linear and quadratic potential. A comparison with the exact solution for a piecewise linear potential demonstrates the dependence of the tunneling rate on the exact shape of the potential. Finally, I will mention applications when determining initial conditions for inflation in the landscape. Based on arXiv:1102.4742 [hep-th].

Colloidal Quantum Dot Solar Cells
Earth’s need for clean energy becomes more evident with each demonstration of the shortcomings of fossil and nuclear energy sources. All carbon-free and nuclear-free energy sources will play important roles in our energy future, but only solar energy can in principle provide all of our energy needs. I will describe current market and technology landscapes for photovoltaics, introduce the use of quantum dots (QDs) as electronic materials, and provide an overview of the developing field of colloidal QD-based thin film solar cells. Although many R&D efforts pursue the fabrication of thin film photovoltaic devices from solution-based particle and nanoparticle (QD) starting materials, these efforts often anneal the deposited particle films to create polycrystalline thin films with grain sizes much larger than those of interest for quantum confinement effects. In contrast, we refer to “QD based solar cells” as those which retain their quantum confined optical properties. Attaining good charge carrier transport within films of QDs represents one of several unique challenges
