Latest Niels Bohr Stories
Brett Smith for redOrbit.com - Your Universe Online Researchers from the Niels Bohr Institute have announced the capacity to consistently teleport information between two clouds of gas atoms, according to a report in the journal Nature Physics. "It is a very important step for quantum information research to have achieved such stable results that every attempt will succeed," said co-author Eugene Polzik, professor at the Niels Bohr Institute at the University of Copenhagen. In their...
WATERLOO, ON, March 15, 2013 /PRNewswire/ - Perimeter Institute for Theoretical Physics, in Ontario, Canada, is pleased to announce the re-appointment of Director Neil Turok to a second five-year term at the Institute's helm. In conjunction with the renewal, Perimeter also announced the establishment of the Mike and Ophelia Lazaridis Niels Bohr Chair in Theoretical Physics, with Dr. Turok as the inaugural chairholder. This is the second Perimeter Research Chair to be announced,...
COLLEGE PARK, Md., Dec. 3, 2012 /PRNewswire-USNewswire/ -- The American Institute of Physics' (AIP) Center for History of Physics has opened a new online exhibit on early 20th century physicist Ernest Rutherford, who helped discover the structure of the atom. Titled "Rutherford's Nuclear World," the new web exhibit burrows beneath the simple story of Rutherford's famed discoveries and recreates the mystery and excitement of his world-changing work. The exhibit features audio clips and...
[ Watch the Video ] Orbit of captured electron matches orbit of Jupiter's captured asteroids Rice University physicists have gone to extremes to prove that Isaac Newton's classical laws of motion can apply in the atomic world: They've built an accurate model of part of the solar system inside a single atom of potassium. In a new paper published this week in Physical Review Letters, Rice's team and collaborators at the Oak Ridge National Laboratory and the Vienna University of...
Researchers at the Niels Bohr Institute have combined two worlds – quantum physics and nano physics, and this has led to the discovery of a new method for laser cooling semiconductor membranes. Semiconductors are vital components in solar cells, LEDs and many other electronics, and the efficient cooling of components is important for future quantum computers and ultrasensitive sensors. The new cooling method works quite paradoxically by heating the material! Using lasers, researchers cooled...
Researchers at the Niels Bohr Institute have measured the lifetime of an extremely stable energy level of magnesium atoms with great precision. Magnesium atoms are used in research with ultra-precise atomic clocks. The new measurements show a lifetime of 2050 seconds, which corresponds to approximately ½ hour. This is the longest lifetime ever measured in a laboratory. The results have been published in the scientific journal Physical Review Letters. The experiment consists of...
Quantum communication could be an option for the absolutely secure transfer of data. The key component in quantum communication over long distances is the special phenomenon called entanglement between two atomic systems. Entanglement between two atomic systems is very fragile and up until now researchers have only been able to maintain the entanglement for a fraction of a second. But in new experiments at the Niels Bohr Institute researchers have succeeded in setting new records and...
Papers document history of frontier physics research COLLEGE PARK, Md., July 26, 2011 /PRNewswire-USNewswire/ -- The Niels Bohr Library and Archives of the American Institute of Physics (AIP), has digitized and released online the complete papers of renowned physicist Samuel A. Goudsmit (1902-1978). (Logo: http://photos.prnewswire.com/prnh/20100714/AIPLOGO) The papers, which occupy 39 linear feet of shelf space in the library and contain approximately 69,000 images, are now published on...
Researchers have changed one of the most basic rules of quantum mechanics: observing light behaving as both a wave and a particle -- a "complementarity" rule that asserts that it is impossible to do, even though it is strictly both.In an experiment reported in the journal Science, researchers say the feat "pulls back the veil" on quantum reality in a way that was thought to be prohibited by theory.Quantum mechanics, a counterintuitive branch of physics that deals with atomic-scale...
Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And so the famous paradox: how can we know reality if we cannot measure it without distorting it?An international team of researchers, led by University of Toronto physicist Aephraim Steinberg of the Centre for Quantum Information and Quantum Control, have found a way to do just...

Carl Friedrich Freiherr von Weizsäcker (June 28, 1912 "“ 28 April 2007) was German physicist and philosopher. He was the longest-living member of Werner Heisenberg's research team which investigated nuclear studies in Germany during World War II. Some argue whether he and the team willingly engaged in the development of a nuclear bomb for Germany, or if its failure was intentional because they did not want the Nazi regime to have nuclear weapons. Weizäcker was born in Kiel,...
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...
