A team of University of Chicago scientists ran quantum simulations to develop a new model of the behavior of water at extremely high temperatures and pressures. The computational measurements, published June 18 in the Proceedings of the National Academy of Sciences, should help scientists understand water's role in the makeup of the mantle and potentially in other planets.
Non-locality, Einstein's 'spooky action at a distance', has already been observed between quantum objects separated by more than one kilometer. This achievement is not a surprise -- recent years have seen a major advancement in the quest for non-local systems. In their ''Physical Review Letters'' publication, researchers from the Faculty of Physics, University of Warsaw present a novel and versatile method for creating and detecting such correlations in a many-body system of ultra-cold atoms.
Researchers at QuTech in Delft have succeeded in generating quantum entanglement between two quantum chips faster than the entanglement is lost. Entanglement -- once referred to by Einstein as 'spooky action' -- forms the link that will provide a future quantum internet its power and fundamental security. This opens the door to connect multiple quantum nodes and create the very first quantum network in the world.
A team of physicists at the University of Vermont have discovered a fundamentally new way surfaces can get wet. Their study may allow scientists to create the thinnest films of liquid ever made--and engineer a new class of surface coatings and lubricants just a few atoms thick.
Army scientists proved a decades-old prediction that mixing TNT and novel aluminum nanoparticles can significantly enhance energetic performance. This explosive discovery is expected to extend the reach of US Army firepower in battle.
Magnetic islands, bubble-like structures that form in fusion plasmas, can grow and disrupt the plasmas and damage the doughnut-shaped tokamak facilities that house fusion reactions. Recent research at the US Department of Energy's Princeton Plasma Physics Laboratory has used large-scale computer simulations to produce a new model that could be key to understanding how the islands interact with the surrounding plasma as they grow and lead to disruptions.
Physicists devised a way to determine the electronic properties of thin gold films after they interact with light. The finding may help pave the way for improvements in a range of optical devices.
Some particles that can be in two places at the same time and are not just particles but also waves, in this case, fermions, appear to move in even weirder ways than previously thought. Theoretical physicists at Georgia Tech applied extreme computing power for a week to predict the movements of fermions by including quantum optics, or light-like, ideas in their mathematical, theoretical modeling.
By comparing different types of remote atomic clocks, physicists at the National Institute of Standards and Technology (NIST) have performed the most accurate test ever of a key principle underlying Albert Einstein's famous theory of general relativity, which describes how gravity relates to space and time.
Scientists use approach analogous to facial-recognition technology to track atomic-scale rearrangements relevant to phase changes, catalytic reactions, and more.
