Quantum theory and consciousness Preface to part 1 (April 12, 2000) Chapter 1. 1.1. 1.6. Atoms are mini black holes? Scientists make teleportation breakthrough. Bye-bye electrons? Circuit made from flowing atoms - tech - 07 April 2011. Time to retire the old soldering iron?
In the "atomtronic" circuits pictured on the right, it is atoms, not electrons, that flow. Such circuits could form the basis for ultra-sensitive gyroscopes. Previously, atoms have been made to flow from one point to another. Dark matter no-show at sensitive underground lab. Celeste Biever, deputy news editor Photosensor arrays meant to capture light produced when dark matter particles interact with xenon atoms (Image: Xenon Collaboration) It's just like a wimp to be a no-show when summoned for interrogation.
That seems to be the result of an experiment to detect the weakly interacting massive particles, or WIMPs, thought to make up elusive dark matter that is thought to make up much of the mass of the universe.

2011 preview: No 'magic' element just yet - physics-math - 24 December 2010. Read more: "In with the New Scientist: Our predictions for 2011" Our calculation suggests we won't reach the fabled "island of stability" at the far depths of the periodic table until 2042 Elements occupying the far depths of the periodic table are so exotic and ephemeral it seems as if they are only barely there.
In early 2010, when physicists announced the creation of the superheavy element ununseptium, even the handful of atoms that were made decayed into smaller ones in a fraction of a second. Theory predicts, however, that superheavy isotopes with lifetimes of minutes can be made. Ethereal quantum state stored in solid crystal - physics-math - 12 January 2011. ETHEREAL quantum entanglement has been captured in solid crystals, showing that it is more robust than once assumed.
These entanglement traps could make quantum computing and communication more practical. In the quantum world, two or more objects can be entangled so that measuring one affects the outcome of measuring the others, no matter how far apart the objects are. This property is central to quantum cryptography, where it allows two people to be sure a secret key they shared was not intercepted, and to quantum computing, as entangled bits occupy a superposition of two or more states at once and so can be used to solve some problems much faster than conventional computers.
A missing element is memory, which is needed to do complex calculations and to transmit quantum states over large distances. First silicon entanglement will aid quantum computing - physics-math - 19 January 2011. The state of entanglement has been created in silicon for the first time.
The feat could lead to quantum computers made like ordinary computer chips. Particles in the quantum realm are entangled if the act of measuring one affects the state of the others, no matter how distant they are. As entangled particles can be in two or more states at once, the phenomenon is key to quantum computing. That's because it lets you work with many potential values simultaneously. But entanglement has been difficult to create in silicon. Atomic disguise makes helium look like hydrogen - physics-math - 28 January 2011. Read more: Click here to read the original version of this story In a feat of modern-day alchemy, atom tinkerers have fooled hydrogen atoms into accepting a helium atom as one of their own.
The camouflaged atom behaves chemically like hydrogen, but has four times the mass of normal hydrogen, allowing predictions for how atomic mass affects reaction rates to be put to the test. A helium atom consists of a nucleus containing two positively charged protons and two neutrons, encircled by two orbiting electrons which carry a negative charge. A hydrogen atom has just one proton and one electron. Donald Fleming of the University of British Columbia in Vancouver, Canada, and colleagues managed to disguise a helium atom as a hydrogen atom by replacing one of its orbiting electrons with a muon, which is far heavier than an electron. How to cook up 'foamy' space-time in the lab - physics-math - 31 January 2011.
Can the way the universe behaves at the tiniest scales be recreated in the laboratory?
Physicist Igor Smolyaninov of the University of Maryland in College Park has a recipe for cooking up a lab-scale version of a "quantum foam", the choppy substance that constitutes space-time in some theories of quantum gravity. According to these theories, space-time may appear smooth and curved, but zoom in, and it is actually made of virtual black holes, each just 10-35 metres wide, which flit in and out of existence. To mimic this structure, Smolyaninov suggests exploiting "critical opalescence". Molecules seen rebounding before they hit a surface - physics-math - 18 February 2011. Imagine watching a tennis game in which the ball bounced back before it hit the court.
That's what single atoms have been seen to do for years in a phenomenon known as quantum reflection. Now physicists have performed the feat with molecules. The bizarre bouncing arises because quantum particles behave like waves rather than single, defined points. LHC not yet a supersymmetry killer. Anil Ananthaswamy, consultantWhen asked about his views on the Large Hadron Collider (LHC) finding the Higgs boson, which is thought to give all elementary particles their mass, Nobel laureate Steven Weinberg confessed: "I'm terrified.
Discovering just the Higgs would really be a crisis. " The key word here is "just". Weinberg and almost every other physicist is hoping that, besides the Higgs, the LHC at CERN near Geneva in Switzerland, will find evidence of something called supersymmetry, or SUSY - an extension to the standard model of particle physics in which every known particle has a super-partner. Quarks have squarks, gluons have gluinos, for instance. SUSY is needed to iron out some really vexing issues, including the hierarchy problem, which causes the standard model to predict a mass for the Higgs that is about 17 to 18 orders of magnitude greater than what experimental clues say it should be.
"This isn't great news for supersymmetry," writes Philip Tanedo in the US/LHC Blogs. Scientists Discover Time Teleportation. Beam Me Up: 'Teleportation' Is Year's Biggest Breakthrough - FoxNews.com. Crew members on the Starship Enterprise beamed to alien planets via teleporters. Now scientists are perfecting a way to communicate via a similar technology.NBC Thanks to physics, and the truly bizarre quirks of quarks, those Star Trek style teleporters may be more than fiction. A strange discovery by quantum physicists at the University of California Santa Barbara means that an object you can see in front of you may exist simultaneously in a parallel universe -- a multi-state condition that has scientists theorizing that teleportation or even time travel may be much more than just the plaything of science fiction writers.
Until this year, all human-made objects have moved according to the laws of classical mechanics, the rules governing ordinary objects. Teleportation. Teleportation is the name given by science fiction writers to the feat of making an object or person disintegrate in one place while a perfect replica appears somewhere else. How this is accomplished is usually not explained in detail, but the general idea seems to be that the original object is scanned in such a way as to extract all the information from it, then this information is transmitted to the receiving location and used to construct the replica, not necessarily from the actual material of the original, but perhaps from atoms of the same kinds, arranged in exactly the same pattern as the original.
A teleportation machine would be like a fax machine, except that it would work on 3-dimensional objects as well as documents, it would produce an exact copy rather than an approximate facsimile, and it would destroy the original in the process of scanning it. In 1993 an international group of six scientists, including IBM Fellow Charles H. C.H. Bennett, G. Experimental Articles. New kind of light created in physics breakthrough. Physicists have created a new kind of light by chilling photons into a blob state. Just like solids, liquids and gases, this recently discovered condition represents a state of matter. Called a Bose-Einstein condensate, it was created in 1995 with super-cold atoms of a gas, but scientists had thought it could not be done with photons, which are basic units of light. First frictionless superfluid molecules created.
Randy Wayne takes new look at relativity. When resolving why electrons can never beat the speed limit set by light, it might be best to forget about time. Thanks to insight from studying movement inside a biological cell, it seems that light itself -- not the relativity of time -- may be the traffic cop, according to a Cornell biologist. Any space with a temperature above absolute zero consists of photons. Molecules with Silly or Unusual Names. Wave–particle duality. Origin of theory[edit] Quantum tunnelling. Ionization.

Large Hadron Collider (LHC) generates a 'mini-Big Bang' 8 November 2010Last updated at 11:12 ET By Katia Moskvitch Science reporter, BBC News Dr David Evans: "From conception to design and building this, it's taken about 20 years. " The Large Hadron Collider has successfully created a "mini-Big Bang" by smashing together lead ions instead of protons. How the universe evolved from a liquid. For One Tiny Instant, Physicists May Have Broken a Law of Nature. This image of a full-energy collision between gold ions shows the paths taken by thousands of subatomic particles produced during the impact.
For a brief instant, it appears, scientists at Brookhaven National Laboratory on Long Island recently discovered a law of nature had been broken. Action still resulted in an equal and opposite reaction, gravity kept the Earth circling the Sun, and conservation of energy remained intact. Six new isotopes of the superheavy elements discovered.
