LaBr3 detector modules for Next Generation PET scanners

On the left is a schematic of adjacent modules with overlapping photomultiplier tubes while the right is a photograph of a single module with PMT's and 8-mm thick light guide.  Improvements in timing resolution for time-of-flight PET is the research of Adjunct Prof. Joel Karp in Penn Radiology.

Topological Insulators

This image shows the valence and conduction bands in the phase transition from topological insulator to conventional insulator with increasing tensile strain.


Quintic Calabi-Yau manifold

In superstring theory, the fundamental building block is an extended object, namely a string, whose vibrations would give rise to the particles encountered in nature. In order to solve certain classic problems of unified gauge theories, the 4-dimensional effective theory should be in a space which is a Calabi-Yau manifold of complex dimension 3.


Protein Design

Penn researchers including Penn physicists Marija Drndic and Jay Kikkawa have designed  specialized protein molecules that organize around carbon nanotubes into an atomistically-predefined pattern. Targeted design of such self-organization is a powerful tool for engineering at the nano scale. 


Outreach Effort for Penn Physics and Astronomy

At the Penn Summer Science Academy (PSSA) students listen to a lecture, delivered from CERN by Professor Elliot Lipeles, on the discovery of a Higgs-like particle the day after the international announcement.
