Majorana Fermions, Topological Insulators and Superconductors
Magnetic diffraction pattern for a Josephson junction with a topological insulator weak link. Building on a theoretical description published in 2008 by Prof. Charles Kane and Liang Fu at Penn, Stanford researchers believe the unusual behavior is explained in terms of Majorana fermions.
High-Bay Space at DRL
This cube-shaped building sits just east of DRL. The high-bay provides faculty and students a facility for research, fabrication, and telescope display. The building has a 42 foot high ceiling, exposed structural steel framing, and a crane beam and glass sliding doors for moving large telescopes in and out. It was completed in January 2012.
Dark Energy Survey
The Dark Energy Survey (DES) uses a 570-Megapixel digital camera at the Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory in the Chilean Andes to probe the origin of the accelerating universe. Penn scientists are among the 120 scientists from 23 institutions in the US, UK, Brazil, and Germany working on the project slated for first light in Fall 2012.
A synthetic peptide candidate that can be used for single molecule electronic measurements. Single molecules can act as a functioning part of a field effect transistor device as studied in Professor Charlie Johnson's lab.
Large Synoptic Survey Telescope at Night
A simulated night sky provides a background for the LSST facilities building on Cerro Pachón. The LSST will carry out a deep, 10 year imaging survey in six broad optical bands over the main survey area of 18,000 square degrees. Penn physicists play important roles in the leadership and anticipated dark energy science that will come from LSST.
After a two-year hiatus, the Large Hadron Collider at the European Organization for Nuclear Research, or CERN, is gearing up for its second run. The LHC enabled the 2012 discovery of the Higgs boson, which gives mass to all particles, but the world’s most complicated scientific apparatus is far from finished.
