Micro-macro entangled 'cat states' could one day test quantum gravity
Physicists eye neural fly data, find formula for Zipf's law
Physicists have identified a mechanism that may help explain Zipf's law – a unique pattern of behavior found in disparate systems, including complex biological ones. The journal Physical Review Letters is pub ...
Quantum-to-classical transition may be explained by fuzziness of measurement references
How did evolution optimize circadian clocks?
Using black holes to measure the Universe's rate of expansion
(Phys.org)—Prof. Hagai Netzer of Tel Aviv University has developed a method that uses black holes to measure distances of billions of light years with a high degree of accuracy. The ability to measure these ...
Hubble bubble may explain different measurements of expansion rate of the universe
The existence of the "Hubble Bubble" may explain, at least in part, the differing measurements for the expansion and therefore the age of the universe. That is the assumption of a team of physicists headed by Prof. Dr. Luca ...
Physicists propose measure of macroscopicity; Schrodinger's cat scores a 57
Deceptive-looking vortex line in superfluid led to twice-mistaken identity
(Phys.org) —So long, solitons: University of Chicago physicists have shown that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the presence ...
Massive neutrinos may not bring about cosmological concordance after all
Researchers build fully mechanical phonon laser
New approach enhances quantum-based secure communication
University of Calgary scientists have overcome an 'Achilles' heel' of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets.
Theorists predict new state of quantum matter may have big impact on electronics
Constantly losing energy is something we deal with in everything we do. If you stop pedaling a bike, it gradually slows; if you let off the gas, your car also slows. As these vehicles move, they also generate ...
Quantum measurement carries information even when the measurement outcome is unread
Scientists identify a mathematical 'crystal ball' that may predict calamities
Neuroscientists have come up with a mathematical equation that may help predict calamities such as financial crashes in economic systems and epileptic seizures in the brain.
