Dark Energy Alternatives to Einstein Are Running out of Room
January 9, 2013 — Astronomers have found that a popular alternative to Albert Einstein's theory for the acceleration of the expansion of the universe does not fit newly obtained data on a fundamental constant, the ... > full story -
News from the World of Quantum Physics: A Non-Causal Quantum Eraser
January 9, 2013 — Whether a quantum object behaves like a wave or like a particle depends (according to the Copenhagen interpretation) on the choice of measurement apparatus used for observing the system, and ... > full story -
Testing Einstein's Famous Equation E=mc2 in Outer Space
January 8, 2013 — A team of physicists have stirred the physics community with an intriguing idea yet to be tested experimentally: The world's most iconic equation, Albert Einstein's E=mc2, may be correct or not ... > full story -
New Antimatter Trapping Method to Provide 'a Major Experimental Advantage'
January 7, 2013 — Researchers have proposed a method for cooling trapped antihydrogen which they believe could provide 'a major experimental advantage' and help to map the mysterious properties of antimatter that have ... > full story -
A Mathematical Study of the Famous Dirac Equation That Describes Particles
January 7, 2013 — In 1928 the British physicist Paul Dirac put forward one of the fundamental equations that we use today to mathematically describe a spin one-half particle from a relativistic point of view. The ... > full story -
New Phase in Reading Photons

A Temperature Below Absolute Zero: Atoms at Negative Absolute Temperature Are the Hottest Systems in the World
January 4, 2013 — On the absolute temperature scale, which is used by physicists and is also called the Kelvin scale, it is not possible to go below zero – at least not in the sense of getting colder than zero ... > full story -
Secure Communication Technology Can Conquer Lack of Trust
January 2, 2013 — Many scenarios in business and communication require that two parties share information without either being sure if they can trust the other. Examples include secure auctions and identification at ... > full story -
Measurements Hint Why the Universe Is Dominated by Matter, Not Anti-Matter
December 26, 2012 — Physicists have made a precise measurement of elusive, nearly massless particles, and obtained a crucial hint as to why the universe is dominated by matter, not by its close relative, ... > full story -
Powerful New Tool Is Quantum Analog of Phase Space Flow
December 26, 2012 — Physicists have found that a new powerful tool they call 'Wigner flow' is the quantum analog of phase space flow. Wigner flow provides information for quantum dynamics similar to that gleaned from ... > full story
