University of Toronto Engineering researchers have demonstrated proof-of-principle for a device that could serve as the backbone of a future quantum Internet. U of T professor Hoi-Kwong Lo and his collaborators have developed a prototype for a key element for all-photonic quantum repeaters, a critical step in long-distance quantum communication.
In a discovery that could provide new insights into the origin of mass in the universe following the Big Bang, scientists have used experiments with kaons and helium-3 to experimentally demonstrate, for the first time, the existence of an exotic nucleus containing two protons and a bound kaon.
Feature describes prototype of new device that mitigates disruption of fusion plasmas faster than the most developed techniques today.
Russian scientists have developed a new method for synthesizing para-carboxyplenylsiloxanes, a unique class of organosilicon compounds. The resulting compounds are promising for creating self-healing, electrically conductive, heat- and frost-resistant silicones.
An international research group has developed a new X-ray spectroscopy method based on the classical double-slit experiment to gain new insights into the physical properties of solids.
Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been fully understood. Physicists at Goethe University have now modelled what are known as topological insulators with the help of ultracold quantum gases. In the current issue of Physical Review Letters, they demonstrate how the edge states could be experimentally detected.
Sudden bursts of heat that can damage the inner walls of tokamak fusion experiments are a hurdle that operators of the facilities must overcome. Such bursts, called 'edge localized modes (ELMs),' occur in doughnut-shaped tokamak devices that house the hot, charged plasma that is used to replicate on Earth the power that drives the sun and other stars. Now researchers at the US Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have directly observed a possible and previously unknown process that can trigger damaging ELMs.
Experimental proof of a decades-old prediction opens a pathway to recreate possible conditions of the early universe here on earth.
If a plasma comes in contact with a solid, under certain circumstances the surface is changed fundamentally and permanently. A team from Kiel University has now discovered a surprising effect, in which the electronic properties of the solid material, such as its electrical conductivity, can be changed in a controlled, extremely fast and reversible manner, by ion impact. Their results were published in the journal Physical Review Letters.
Lehigh University's Rosi Reed presents findings from new Beam Energy Scan at Brookhaven National Lab's Relativistic Heavy Ion Collider that tests the limits of quark-gluon plasma (QGP), the mysterious liquid thought to have existed in the micro-seconds after the Big Bang
