LIGHT GOES INFINITELY FAST WITH NEW ON-CHIP MATERIAL
LIGHT GOES INFINITELY FAST ON-CHIP MATERIAL
2015/11/12
Electrons are so 20th century. In the 21st century, photonic devices, which use light to transport large amounts of information quickly, will enhance or even replace the electronic devices t...
Differential Light Shift Cancellation in a Magnetic-Field-Insensitive Transition of $^{87}$Rb
Differential Light Shift Cancellation Magnetic-Field-Insensitive Transition
2010/10/29
We demonstrate near-complete cancellation of the differential light shift of a two-photon magnetic-field-insensitive microwave hyperfine (clock) transition in $^{87}$Rb atoms trapped in an optical la...
Nanotechnology offers the promise of a new wave of sensors and optical components, but the tiny sizes involved can make it difficult for users to exchange information with these devices. Now, research...
Results from a Search for Light-Mass Dark Matter with a P-type Point Contact Germanium Detector
Light-Mass Dark Matter P-type Point
2010/3/16
We report on several features present in the energy spectrum from an ultra low-noise germanium detector operated at 2,100 m.w.e. By implementing a new technique able to reject surface events, a number...
Dispersion supported BB84 quantum key distribution using phase modulated light
PM-PM phase modulated light quantum key
2010/3/10
We propose and experimentally demonstrate that, contrary to what it was thought up to now, BB84 operation is feasible using the double phase modulator (PM-PM) configuration in frequency coded systems....
The electromagnetic current of spin-1 composite particles does not transform properly under rotations if only the valence contribution is considered in the light-front model. In particular, the plus c...
