Protons hog the momentum in neutron-rich nuclei
Like dancers swirling on the dance floor with bystanders looking on, protons and neutrons that have briefly paired up in the nucleus have higher-average momentum, leaving less for non-paired nucleons. Using ...
Scientists show how to erase information without using energy
Could the combination of general relativity and quantum mechanics lead to spintronics?
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.
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.
Black hole that doesn't emit x-rays discovered near massive star
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 ...
Scientists score one more victory over uncertainty in quantum physics measurements
(PhysOrg.com) -- Most people attempt to reduce the little uncertainties of life by carrying umbrellas on cloudy days, purchasing automobile insurance or hiring inspectors to evaluate homes they might consider ...
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.
Physicists use metamaterials to observe giant photonic spin Hall effect
(Phys.org) —Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have once again demonstrated the incredible capabilities of metamaterials – artificial ...
Integrated optical vortices on a chip (w/ Video)
An international research group led by scientists from the University of Bristol and the Universities of Glasgow (UK) and Sun Yat-sen and Fudan in China, have demonstrated integrated arrays of emitters of ...
Physicists create nanoscale spinning magnetic droplets
Researchers have successfully created a magnetic soliton – a nano-sized, spinning droplet that was first theorized 35 years ago. These solitons have implications for the creation of magnetic, spin-based computers.
Researchers find way to measure speed of spinning object using light's orbital angular momentum
Study resolves century-long debate over how to describe electromagnetic momentum density in matter
(PhysOrg.com) -- Researchers from the NIST Center for Nanoscale Science and Technology and the University of British Columbia have shown that the interaction between a light pulse and a light-absorbing object, including the ...
