The Sociedade Brasileira de Fisica (SBF) and the American Physics Society (APS) are pleased to announce the launch of a new exchange program for physics graduate students and professors in the U.S. and Brazil.
Through the Brazil- U.S. Physics student visitation program, graduate students in the U.S. and Brazil can apply for funds to travel to the other country in order to pursue a breadth of opportunities in physics. Such opportunities might include: 1) attending a short course seminar or summer institute; 2) visiting with a professor in his/her field of study; 3) working temporarily in a laboratory; or 4) any other opportunity that the student and professor believe is worthy of travel support. Grants for students are for up to $3,000.
The Brazil-U.S. Professorship/Lectureship Program funds physicists in Brazil and the United States wishing to visit overseas to teach a short course or deliver a lecture series in the other country. The professorship grants are for up to $4,000.
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, 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
The Winston Churchill Foundation of the United States chose Fleming, from Crescent Springs, Ky., as one of 14 students from 103 US colleges and universities to receive the prestigious scholarship this year. The foundation was founded in 1959 at the recommendation of Sir Winston Churchill, who wished there would always be American graduate students at the college named in his honor.
“It’s great to have a chance to live and work abroad, meet researchers from other parts of the world and learn how they conduct research,” said the 22-year-old Fleming, who will earn a Master of Philosophy degree.
At Case Western Reserve, Fleming, who is majoring in physics and biochemistry, has been probing how cells in the human defense system sort out chemical signals and navigate to infection. Fleming is the only investigator who was chosen for the project as a first-year student.
This year the physics department has two nominees for the 2011 Carl F. Wittke Award for Excellence in Undergraduate Teaching. Faculty are nominated by undergraduate students and recent alums; these prestigious awards are presented each year during Commencement. Congratulations to Professors Corbin Covault and Diana Driscol.
