Squeezed light from single atoms
(PhysOrg.com) -- Max Planck Institute of Quantum Optics scientists generate amplitude-squeezed light fields using single atoms trapped inside optical cavities.
A quiet phase: NIST optical tools produce ultra-low-noise microwave signals
By combining advanced laser technologies in a new way, physicists at the National Institute of Standards and Technology (NIST) have generated microwave signals that are more pure and stable than those from ...
Nanotubes pose health risk, study shows
(PhysOrg.com) -- Tiny fibres used to strengthen items such as bike frames and hockey sticks could pose risks to workers who make them.
Researchers develop integrated nanomechanical sensor for atomic force microscopy
(PhysOrg.com) -- The atomic force microscope (AFM) is an important tool for nanoscale surface metrology. Typical AFMs map local tip-surface interactions by scanning a flexible cantilever probe over a surface. ...
When the speed of light depends on its direction
Light does not travel at the same speed in all directions under the effect of an electromagnetic field. Although predicted by theory, this counter-intuitive effect has for the first time been demonstrated ...
