A Sub-femtosecond Stop Watch for 'Photon Finish' Races (3/16/2008)

A Sub-femtosecond Stop Watch for 'Photon Finish' RacesUsing a system that can compare the travel times of two photons with sub-femtosecond precision, scientists at the Joint Quantum Institute (a partnership of the National Institute of Standards and Technology (NIST) and the University of Maryland) and Georgetown University have found a remarkably large difference in the time it takes photons to pass through nearly identical stacks of materials with different arrangements of refractive layers. The technique, described at the annual March Meeting of the American Physical Society,* ultimately could provide an empirical answer to a long-standing puzzle over how fast light crosses narrow gaps that do not permit the passage of conventional electromagnetic waves. ...> Full Article


New detector can 'see' single neutrons over broad range (3/15/2008)

New detector can 'see' single neutrons over broad rangeResearchers have developed a new optical method that can detect individual neutrons and record them over a range of intensities at least a hundred times greater than existing detectors. The new detector promises to improve existing neutron measurements and enable tests of new phenomena beyond the Standard Model, the basic framework of particle physics. ...> Full Article
