Scientists create never-before-seen form of matter
Harvard and MIT scientists are challenging the conventional wisdom about light, and they didn't need to go to a galaxy far, far away to do it.
Manipulating Lorentz and Fano spectral line shapes
Nanoparticle trapped with laser light temporarily violates the second law of thermodynamics
Objects with sizes in the nanometer range, such as the molecular building blocks of living cells or nanotechnological devices, are continuously exposed to random collisions with surrounding molecules. In ...
A new laser for a faster internet
(Phys.org) —A new laser developed by a research group at Caltech holds the potential to increase by orders of magnitude the rate of data transmission in the optical-fiber network—the backbone of the Internet.
Team develops new, inexpensive transparent projection screen (w/ Video)
Picture the Louvre pyramid: the iconic glass pyramid that serves as main entrance and skylight to the landmark museum. The pyramid is illuminated at night, creating a magical ambience. Imagine strolling next ...
Tiny lasers light up future electronics
(Phys.org) —Faster, smaller electronics are one step closer with researchers from The Australian National University successfully making the first room temperature lasers from gallium arsenide nanowires.
Topological insulators: Persuading light to mix it up with matter
Researchers at MIT have succeeded in producing and measuring a coupling of photons and electrons on the surface of an unusual type of material called a topological insulator. This type of coupling had been ...
Researchers devise a way to mimic gravitational lensing in a way that can be seen
SLAC scientists create twisted light
(Phys.org) —Scientists at SLAC have found a new method to create coherent beams of twisted light – light that spirals around a central axis as it travels. It has the potential to generate twisted light ...
Fastest rotating man-made object created
(Phys.org) —A team of researchers at the University of St Andrews has created the world's fastest spinning man-made object.
NIST ytterbium atomic clocks set record for stability
A pair of experimental atomic clocks based on ytterbium atoms at the National Institute of Standards and Technology (NIST) has set a new record for stability. The clocks act like 21st-century pendulums or ...
'Groovy' hologram creates strange state of light at visible and invisible wavelengths
(Phys.org) —Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like ...
