Theory of Everything
The universe could possibly have more dimensions. Here's how.  LIVE SCIENCE · 1 day
String theory is a purported theory of everything that physicists hope will one day explain … everything. more
10,000 times faster calculations of many-body quantum dynamics possible  SCIENCE DAILY · 5 days
How an electron behaves in an atom, or how it moves in a solid, can be predicted precisely with the equations of quantum mechanics. These theoretical calculations agree with the... more
10,000 times faster calculations of many-body quantum dynamics possible  PHYS.ORG · 5 days
How an electron behaves in an atom, or how it moves in a solid, can be predicted precisely with the equations of quantum mechanics. These theoretical calculations agree fully with... more
ALPHA collaboration reports first measurements of certain quantum effects in antimatter  PHYS.ORG · 5 days
The ALPHA collaboration at CERN has reported the first measurements of certain quantum effects in the energy structure of antihydrogen, the antimatter counterpart of hydrogen. These... more
Deconstructing Schrödinger's cat  SCIENCE DAILY · 2 weeks
Many physicists have attempted to explain the problem of quantum superposition, as exemplified by Schrödinger's cat. Now a French theoretical physicist proposes a novel possible solution, which combines two different approaches and brings in universal gravitation. more
The emergence of small-scale self-affine surface roughness from deformation  Science Magazine · 2 weeks
Most natural and man-made surfaces appear to be rough on many length scales. There is presently no unifying theory of the origin of roughness or the self-affine nature of surface... more
Deconstructing Schrödinger's cat  PHYS.ORG · 2 weeks
The paradox of Schrödinger's cat—the feline that is, famously, both alive and dead until its box is opened—is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seem to predict that macroscopic objects (like cats)... more
Imaging through noise with quantum illumination  Science Magazine · 3 weeks
The contrast of an image can be degraded by the presence of background light and sensor noise. To overcome this degradation, quantum illumination protocols have been theorized that exploit the spatial correlations between photon pairs. Here,... more
Researchers demonstrate optical backflow of light  PHYS.ORG · 3 weeks
Researchers at Tel Aviv University have for the first time demonstrated the backflow of optical light propagating forward. The phenomenon, theorized more than 50 years ago by quantum physicists, has never before been demonstrated successfully in... more
Astronomers search for gravitational-wave memory  PHYS.ORG · 3 weeks
Astronomers regularly observe gravitational waves (GW)—ripples in space and time—that are caused by pairs of black holes merging into one. Einstein's theory of gravity predicts that GW, which squeeze and stretch space as they pass, will permanently distort... more
How nature tells us its formulas  PHYS.ORG · 3 weeks
Many of the biggest questions in physics can be answered with the help of quantum field theories: They are needed to describe the dynamics of many interacting particles, and thus they are just as important in... more
Showing how the tiniest particles in our Universe saved us from complete annihilation  PHYS.ORG · 3 weeks
Recently discovered ripples of spacetime called gravitational waves could contain evidence to prove the theory that life survived the Big Bang because... more
Heisenberg limit gets a meaningful update  PHYS.ORG · 3 weeks
One of the cornerstones of quantum theory is a fundamental limit to the precision with which we can know certain pairs of physical quantities, such as position and momentum. For quantum theoretical treatments, this uncertainty principle... more
How supercomputers are helping us link quantum entanglement to cold coffee  PHYS.ORG · 4 weeks
Theoretical physicists from Trinity College Dublin have found a deep link between one of the most striking features of quantum mechanics—quantum entanglement—and thermalisation, which is the... more
Calculating Hawking radiation at the event horizon of a black hole  PHYS.ORG · 4 weeks
A RUDN University physicist has developed a formula for calculating Hawking radiation on the event horizon of a black hole, which allows physicists to determine how... more
Astronomers witness the dragging of space-time in stellar cosmic dance  PHYS.ORG · 4 weeks
An international team of astrophysicists led by Australian Professor Matthew Bailes, from the ARC Centre of Excellence of Gravitational Wave Discovery (OzGrav), has shown exciting new evidence for... more
Theoretical study points to jade-like materials as quantum spin liquids  nanowerk · 4 weeks
This exotic liquid-like state of matter in which magnetism never freezes could give rise to high-temperature superconductivity and form the basis for quantum computing. more
