Self-assembling Building Blocks
Self-assembling building blocks occur in a diverse set of supramolecular, macromolecular, and other complex systems that impact numerous fields such as industrial dyes and pigments, xerographic receptors, organic semiconductors, transistors, light-emitting diodes and solar cells. Prof. Paul Heiney collaborates with chemists and material scientists on the study of such molecular systems.
Nanoscale Electronic Nose
Prof. Charlie Johnson's group at Penn have coupled olfactory receptor proteins from mice to carbon nanotubes to create a prototype electronic nose. Olfactory receptors are embedded in nanodiscs that mimic the environment of the olfactory cell membrane. Odorant molecules bind to the receptor, which produces an electrical response in the carbon nanotube (gray cylinder).
Penn physicists study graphenes, atomically thin sheets of carbon atoms in a honeycomb lattice. Graphene is the prototype Dirac material hosting a solid state realization of an ultra-relativistic electron gas and accessing new phenomena that are controlled by electric and magnetic fields and by the atomic registry when graphenes are stacked.
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.
Thursday, December 8, the Physics and Astronomy Department will host the second
Annual Women in Physics Public Lecture, to be delivered by Prof. Alessandra
Buonanno, Director at Max Planck Institute for Gravitational Physics. The event
is made possible by a Fund to Encourage Women grant.
Vijay Balasubramanian, Professor of Physics and Astronomy, is a Principal Investigator in the “It from Qubit” project which includes institutions across the United States and in Canada, Israel, Japan, the United Kingdom and Argentina. The project is investigating the idea that the fabric of spacetime is knitted together by quantum entanglement. Utilizing the sciences of quantum computers and the study of space time and general relativity, Vijay hopes to discover the components that make up space time and decode the quantum nature of large-scale events in the cosmos.
Masao Sako and Gary Bernstein
of Physics and Astronomy and Physics majors Paul Chichura, Paulina Destarac,
Tongtian Liu, William Saunders, and Tarmily Wen, have found a dwarf planet
candidate in our Solar System using data from the Dark Energy Survey.
This object is currently 8.5 billion miles
away, making it the second farthest known member of the Solar System.
The analysis of the measurement of its size is underway.
