Ex nihilo: Dynamical Casimir effect in metamaterial converts vacuum fluctuations into real photons
New LED packaging technology improves performance
New way to store light could prove useful for optical communication
Vertical cavity quantum switch could lead us away from electronics-based computing
Could light and matter coupling lead to quantum computation?
Quantum non-demolition measurement allows physicists to count photons without destroying them
'Photon glue' enables a new quantum mechanical state
(Phys.org) —Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials.
Parasitic wasps use calcium pump to block fruit fly immunity
Parasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies' blood cells, a finding that offers new insight into how pathogens break through a host's defenses.
The world's most stable laser also promises heightened test precision
(Phys.org)—The world's most stable laser – with frequency variation of no more than 2 parts in 10,000 trillion – has been developed and tested by an international collaboration of scientists at NIST/JILA ...
Good vibrations: Researchers record first direct observations of quantum effects in an optomechanical system
A long-time staple of science fiction is the tractor beam, a technology in which light is used to move massive objects – recall the tractor beam in the movie Star Wars that captured the Millennium Falcon ...
First 3D nanoscale optical cavities from metamaterials hold promise for nanolasers, photonic communications
(Phys.org) -- The worlds smallest three-dimensional optical cavities with the potential to generate the worlds most intense nanolaser beams have been created by a scientific team led by researchers ...
Transparent iron? For the first time, an experiment shows that atomic nuclei can become transparent
At the high-brilliance synchrotron light source PETRA III, a team of DESY scientists headed by Dr. Ralf Röhlsberger has succeeded in making atomic nuclei transparent with the help of X-ray light. At the ...
Engineers at Yale develop new type of mechanical memory
Print your own lasers, lights and TV screens
Imagine printing your own room lighting, lasers, or solar cells from inks you buy at the local newsagent. Jacek Jasieniak and his colleagues at CSIRO, the University of Melbourne and the University of Padua ...
