Quantum calculations can make atomic clocks of the future far more accurate

May 6, 2011 - New calculations of how atoms swell when they’re warmed up can help make the next generation of atomic clocks 10 times more precise. The current precision champ, the quantum-logic clock developed

UD VERITAS group discovers gamma-rays from the remnant of Tycho's Supernova

March 15, 2011 - Using the VERITAS gamma-ray telescope array in Arizona, graduate student Dana Saxon has detected high energy gamma-ray emission from the expanding remnant of a  supernova explosion which was observed by the Danish astronomer Tycho Brahe in 1572.

CNN reports on Hadjipanayis Lab participation in the race to make the world's strongest magnet

March 9, 2011 - George Hadjipanayis' assistant came to him with perplexing news: Some incredibly strong magnetic field had caused their lab instruments to go haywire. "You're out of your mind," Hadjipanayis recalls telling him in the early 1980s. "You have something wrong; go back" and try the experiment again. Nothing was wrong, though, and Hadjipanayis soon realized that his team accidentally had created what was then, and continues to be, the world's strongest magnet -- made of a strange and little understood "rare earth" element called neodymium.

UD researchers help complete world's largest neutrino observatory in ice!

December 20, 2010 - Culminating a decade of planning, innovation and testing, construction of the world's largest neutrino observatory, installed in the ice at the geographic South Pole, was successfully completed Dec. 18, 2010, New Zealand time. The last of 86 holes had been drilled and a total of 5,160 optical sensors are now installed to form a cubic kilometer of instrumented ice -- of the IceCube Neutrino Observatory -- located at the National Science Foundation's Amundsen-Scott South Pole Station.

The prospect for quantum-interference-controlled molecular electronics utilizing graphene nanoribbons

December 8, 2010 - In the recent Physical Review Letters article, Prof. Nikolic and postdoctoral researcher Dr. Kamal K. Saha  have proposed a new type of molecular-scale devices where a single ring-shaped organic molecule is connected to electrodes made of graphene nanoribbons (see illustration on the right).
