New Light Shed On Mystery Mechanism That Allows Positive And Negative Charges To Be Separated Efficiently
2013-12-13 10:17:11

University of Cambridge By using an ultrafast camera, scientists say they have observed the very first instants following the absorption of light into artificial yet organic nanostructures and found that charges not only formed rapidly but also separated very quickly over long distances - phenomena that occur due to the wavelike nature of electrons which are governed by fundamental laws of quantum mechanics. This result surprised scientists as such phenomena were believed to be limited...

Wormholes Driving Quantum Entanglement
2013-12-04 15:25:47

John P. Millis, PhD for redOrbit.com - Your Universe Online One of the strangest consequences of quantum theory, is what happens when elementary particles are created in pairs. These individual charges become entangled with their counterparts. The result is that interactions with one of these particles creates direct consequences for the other, even if the other particle is on the other side of the Universe. The simplest example of this is when an electron and positron are created when...

Making Magnets With Ultra Cold Atoms
2013-11-27 16:53:05

University of Hamburg Magnets have fascinated mankind for millenia. From the Greek philosophers to scientists of the modern era, which saw the rise of quantum mechanics, magnets have been pondered and investigated. Nowadays, they are not only intriguing oddities of nature, but also constitute crucial building blocks of modern technology: Ranging from data storage over medical instrumentation to transportation. And yet, to this day, they continue to puzzle scientists. A novel approach to...

Decay Used To Create Quantum Information
2013-11-25 09:47:26

University of Copenhagen - Niels Bohr Institute Usually, when researchers work with quantum information, they do everything they can to prevent the information from decaying. Now researchers at the Niels Bohr Institute, among others, have flipped things around and are exploiting the decay to create the so-called entanglement of atomic systems, which is the foundation for quantum information processing. The results are published in the scientific journal, Nature. "When working with...

International Research Team Shows Distant Artificial Atoms Cooperate By Sharing Light
2013-11-14 15:52:07

University of Calgary Work is expected to have future applications in advanced quantum devices An international team of scientists has shown for the first time that atoms can work collectively rather than independently of each other to share light. Quantum physicists have long discussed such an effect, but it has not been seen before in an experiment. The team included scientists from ETH Zürich (a leading university in Switzerland) who performed the experiment and theoretical...

Single-Atom Light Switch
2013-11-06 10:32:04

Vienna University of Technology With just a single atom, light can be switched between two fiber optic cables at the Vienna University of Technology. Such a switch enables quantum phenomena to be used for information and communication technology. Fiber optic cables are turned in to a quantum lab: scientists are trying to build optical switches at the smallest possible scale in order to manipulate light. At the Vienna University of Technology, this can now be done using a single atom....

For the past eight years, two French researchers have been bouncing droplets around a vibrating oil bath and observing their unique behavior. What sounds like a high-school experiment has in fact provided the first ever evidence that the strange features of the quantum world can be reproduced on a macroscopic scale. Now, many researchers are asking if the oil-bath experiments can provide insights into quantum mechanics and more specifically why particles can behave as waves and waves can...

Heisenberg's Hunch Was Correct
2013-10-18 08:20:15

John P. Millis, PhD for redOrbit.com - Your Universe Online Students of physics are almost universally perplexed when they are first exposed to the paradoxical world of quantum mechanics. The reason the field is so difficult to wrap one’s mind around is that the behavior of quantum systems is fundamentally different from the macroscopic world in which we spend our lives. One of the guiding principles of the quantum world is a set of statements known as Heisenberg's error-disturbance...

Niels Henrik David Bohr (October 7, 1885 - November 18, 1962) was a Danish physicist. He made essential contributions to understanding atom structure and quantum mechanics. Born in Copenhagen, Denmark to Christian Bohr and Ellen Adler, Bohr got his doctorate at Copenhagen University in 1911. He then studied under Ernest Rutherford in Manchester, England. Based on Rutherford's theories, Bohr published his Bohr model about atom structure in 1913, introducing the theory of electrons...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
