Singh Center for Nanotechnology

The newly-opened (Oct. 4, 2013) 78,000 square-foot Krishna P. Singh Center for Nanotechnology serves as Penn's focal point for nanoscience research and technology-development.  P&A's Prof. Jay Kikkawa was instrumental in the planning and provision of vital services for the new facility.

Vector Bundles on Calabi-Yau Manifolds

Supersymmetric vacua of the heterotic string and M-theory are explored through the study of complex algebraic geometry.  The figure is from a recent paper by Prof. Burt Ovrut and collaborators on the Kahler cone substructure associated with the SU(2) bundle for different Kahler moduli.

DNA-Carbon Nanotube Hybrid

Single-stranded DNA and carbon nanotubes are chemically compatible and readily self-assemble into DNA-carbon nanotube hybrids (pictured here).  These materials have applications in nanoelectronics, medicine, environmental safety and homeland security.  Dr. Robert R. Johnson of the University of Pennsylvania has used computer simulation to study the structure of these nanomaterials.


Molecular Electronics

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.


Dipole magnets at the Large Hadron Collider

Protons at the LHC are accelerated to 7 TeV (the equivalent energy to an electron subjected to the potential of more than 4.5 trillion batteries laid end-to-end).  To circulate such powerful beams of particles, the LHC employs superconducting dipole magnets like those shown to provide a magnetic field almost 100,000 times stronger than the earth's magnetic field.
