Spiral-shaped 'light fan' adds new twist to laser-driven plasma accelerators
Could the combination of general relativity and quantum mechanics lead to spintronics?
Scientists show how to erase information without using energy
Small thunderstorms may add up to massive cyclones on Saturn
For the last decade, astronomers have observed curious "hotspots" on Saturn's poles. In 2008, NASA's Cassini spacecraft beamed back close-up images of these hotspots, revealing them to be immense cyclones, ...
Ultrafast heat conduction can manipulate nanoscale magnets
Researchers at the University of Illinois at Urbana-Champaign have uncovered physical mechanisms allowing the manipulation of magnetic information with heat. These new phenomena rely on the transport of thermal ...
New approach uses 'twisted light' to increase efficiency of quantum cryptography systems
Researchers at the University of Rochester and their collaborators have developed a way to transfer 2.05 bits per photon by using "twisted light." This remarkable achievement is possible because the researchers ...
Forbidden quantum leaps possible with high-resolution spectroscopy
A new twist on an old tool lets scientists use light to study and control matter with 1,000 times better resolution and precision than previously possible.
Twisted light waves sent across Vienna
A group of researchers from Austria have sent twisted beams of light across the rooftops of Vienna.
Black hole that doesn't emit x-rays discovered near massive star
Superconducting spintronics pave way for next-generation computing
A breakthrough for the field of Spintronics, a new type of technology which it is widely believed could be the basis of a future revolution in computing, has been announced by scientists in Cambridge.
Physicists prove Heisenberg's intuition correct
An international team of scientists has provided proof of a key feature of quantum physics – Heisenberg's error-disturbance relation - more than 80 years after it was first suggested.
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 ...
New theory points to 'zombie vortices' as key step in star formation
(Phys.org) —A new theory by fluid dynamics experts at the University of California, Berkeley, shows how "zombie vortices" help lead to the birth of a new star.
