Redefining the kilogram and the ampere
New research using graphene presents the most precise measurements of the quantum Hall effect ever made, one of the key steps in the process to redefine two SI units.
Better 'photon loops' may be key to computer and physics advances
Surprisingly, transmitting information-rich photons thousands of miles through fiber-optic cable is far easier than reliably sending them just a few nanometers through a computer circuit. However, it may soon ...
Researchers create light from 'almost nothing'
Research sheds new light on black holes
(PhysOrg.com) -- The quantum phenomenon which is thought to cause black holes to leak energy and ultimately explode is more common than first thought according to Victoria University researchers.
NIST's new scanning probe microscope is supercool
The discoveries of superconductivity, the quantum Hall effect and the fractional quantum Hall effect were all the result of measurements made at increasingly lower temperatures. Now, pushing the regime of ...
Researchers create high performance infrared camera based on type-II InAs/GaSb superlattices
Researchers at Northwestern University have created a new infrared camera based on Type-II InAs/GaSb superlattices that produces much higher resolution images than previous infrared cameras.
Metamaterials could reduce friction in nanomachines
(PhysOrg.com) -- Nanoscale machines expected to have wide application in industry, energy, medicine and other fields may someday operate far more efficiently thanks to important theoretical discoveries concerning the manipulation ...
Article examines rare quantum physics effect
(PhysOrg.com) -- There's nothing University of Nebraska-Lincoln physicist Herman Batelaan likes more than a challenge. And there are few areas of science more challenging than working at the sub-atomic, or ...
'Nano violin string' made of vibrating carbon nanotube (w/ Video)
Researchers at TU Delft, The Netherlands, have succeeded in measuring the influence of a single electron on a vibrating carbon nanotube. This research can be important for work such as the development of ultra-small ...
Study on free-space optical communication shows experimental evidence of a unique atmospheric effect
Three members of the faculty at Stevens Institute of Technology recently collaborated on a paper focusing on free-space optical communication, which appears in the latest issue of Optics Express.
Nanoscale materials grow with the flow (Videos)
Imagine unloading a pile of bricks onto the ground and watching the bricks assemble themselves into a level, straight wall in only a few minutes. While merely a fantasy for builders in the everyday world, ...
Bose-Einstein condensate could be used to observe quantum mass acquisition
A possible means of observing an exotic quantum effect that imparts mass to a normally massless particle has been proposed by researchers from the RIKEN Center for Emergent Matter Science.
Quantum effects in nanometer-scale metallic structures
Plasmonic devices combine the 'super speed' of optics with the 'super small' of microelectronics. These devices exhibit quantum effects and show promise as possible ultrafast circuit elements, but current ...
