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...

Recipe For Universe Heat Stir

John P. Millis, PhD for redOrbit.com - Your Universe Online For several decades now the leading model for the origin and evolution of the known Universe is a concept known as the Big Bang. Nearly 15 billion years ago, quantum fluctuations of the infinite vacuum of space-time caused the emergence of a rapidly expanding Universe, ultimately filled with matter and radiation. But what initially caused the fluctuation? According to quantum mechanics, it is a natural result of the...

Popular television shows such as “Doctor Who” have brought the idea of time travel into the vernacular of popular culture. But problem of time travel is even more complicated than one might think. LSU’s Mark Wilde has shown that it would theoretically be possible for time travelers to copy quantum data from the past. It all started when David Deutsch, a pioneer of quantum computing and a physicist at Oxford, came up with a simplified model of time travel to deal with the paradoxes...

Ultrashort laser pulses reveal that 'coherence' plays a subtle role in energy transfers Sophisticated recent experiments with ultrashort laser pulses support the idea that intuition-defying quantum interactions between molecules help plants, algae, and some bacteria efficiently gather light to fuel their growth. But key details of nature's vital light-harvesting mechanisms remain obscure, and the exact role that quantum physics may play in understanding them is more subtle than was once...

Growth in Cold and Ultracold Company Market Prompts Move Boulder, Colorado (PRWEB) December 06, 2013 ColdQuanta, Inc. is expanding to a facility two and a half times larger than its current facility. Currently located on Range Street in Boulder, the new facility is less than two miles away at 3030 Sterling Circle. “We have experienced impressive growth in the last two years and have outgrown our current laboratories and office space.” said Rainer Kunz, CEO of ColdQuanta. He added,...

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...

Study sets out to demystify a selected set of objections targeted against quantum theory in the literature A colloquium paper published in EPJ D looks into the alleged issues associated with quantum theory. Berthold-Georg Englert from the National University of Singapore reviews a selection of the potential problems of the theory. In particular, he discusses cases when mathematical tools are confused with the actual observed sub-atomic scale phenomena they are describing. Such tools are...

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...

Exploiting Flaws In Diamond Fragments Paves Way For Nanoscale MRI
2013-11-25 08:02:31

University of Cambridge By exploiting flaws in miniscule diamond fragments, researchers say they have achieved enough coherence of the magnetic moment inherent in these defects to harness their potential for precise quantum sensors in a material that is 'biocompatible'. Nanoscopic thermal and magnetic field detectors - which can be inserted into living cells - could enhance our understanding of everything from chemical reactions within single cells to signalling in neural networks and...

Physics
2014-01-12 00:00:00

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Open Systems & Information Dynamics
2012-05-17 15:20:56

Open Systems & Information Dynamics (OSID) is journal published by World Scientific. The aim of the Journal is to promote interdisciplinary research in mathematics, physics, engineering and life sciences centered around the issues of broadly understood information processing, storage and transmission, in both quantum and classical settings. Our special interest lies in the information-theoretic approach to phenomena dealing with dynamics and thermodynamics, control, communication,...

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...

Multiverse -- The term Multiverse was invented in December 1960, by Andy Nimmo, then vice chairman of the British Interplanetary Society, Scottish Branch, for a talk on the Everett many-worlds interpretation of quantum physics which had been published in 1957, to the branch. This was given in February 1961, and the word with its original definition, "an apparent universe, a multiplicity of which, go to make up the whole universe" was then first used. This was because the then dictionary...
