New particles are usually only found in huge particle accelerators. But something quite similar can be found in a simple lab or in computer simulations: a quasiparticle. It behaves just like a particle, but its existence depends, in some subtle way, on its environment. Scientists in Vienna have now discovered a surprising new quasiparticle called 'pi-ton'.
Researchers at The University of Tokyo show that liquid water has 2 distinct molecular arrangements: tetrahedral and non-tetrahedral. By computer simulations and analysis of X-ray scattering data, the researchers were able to settle a very old controversy in science.
Researchers at the University of British Columbia have demonstrated an entirely new way to precisely control electrical currents by leveraging the interaction between an electron's spin and its orbital rotation around the nucleus.
A team from TU Wien and the University of Heidelberg has developed methods with which these models can be directly obtained from experimental measurements. Instead of comparing the experimental results to theoretical model predictions, it is, in a certain sense, possible to measure the theory itself.
New research by engineers at MIT and elsewhere could lead to batteries that can pack more power per pound and last longer, based on the long-sought goal of using pure lithium metal as one of the battery's two electrodes, the anode.
Within quark-gluon plasma, strange quarks are readily produced through collisions between gluons. In analysis published in EPJ ST, Dr Johann Rafelski presents how our understanding of this characteristic strangeness production signature has evolved over the span of his long career.
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have for the first time created and imaged a novel pair of quantum dots -- tiny islands of confined electric charge that act like interacting artificial atoms. Such "coupled" quantum dots could serve as a robust quantum bit, or qubit, the fundamental unit of information for a quantum computer.
Until now, complex experimental equipment was required to measure the shape of a light pulse. Now, it can be done in a tiny crystal with the size of less than a milimeter. This can be used to study new materials or even even to reliably and quickly detect diseases by examining tiny blood samples.
A team of scientists led by a physicist at the University of California, Riverside, has discovered an electrical detection method for terahertz electromagnetic waves, which are extremely difficult to detect. The discovery could help miniaturize the detection equipment on microchips and enhance sensitivity.
Researchers of Peter the Great St. Petersburg Polytechnic University (SPbPU) in collaboration with colleagues from the Physikalisch Technische Bundesanstalt (PTB) and a number of German scientific organizations, calculated previously unexplored effects in atoms. The results were published in the PHYSICAL REVIEW A, highlighted as an Editor's Choice article.
