Researchers used Einstein's famous E=mc2 equation and the Large Hadron Collider to recreate a miniature version of the event at the origins of our Universe, and the first findings from their work were published in the journal Physical Review Letters. Dr. Andreas Warburton of McGill's Department of Physics made leading contributions to the analysis of data from the experiment, known as "ATLAS," meaning the findings have a special significance for Canadian science.
Warburton and 3171 colleagues from around the world are using the data collected from the recreation in an attempt to look for exotic new particles whose existence is suggested by theoretical calculations. His work may help to revolutionize our understanding of the fundamental components of the Universe.
"Understanding whether new kinds of matter exist or not is interesting because it holds clues to knowledge about how the Universe works fundamentally," Warburton said. "The Standard Model of Particle Physics is a useful theoretical framework but it is known to be flawed and incomplete – we are searching for new particles that lie outside this framework, and we are also seeking to establish the non-existence of these hypothetical particles." The research published this week falls into the latter category and is about determining the mass of a theoretical particle known as an "excited quark."
Warburton offered the following analogy: "By exploring the high-energy subatomic frontier, it is metaphorically somewhat like turning over stones at the seashore and looking for new and interesting surprises hiding under the rocks. Here we are looking under stones that have been too heavy to lift before this summer. What we see or don't see under those stones helps to paint new pictures about how the Universe works and tells us which stones are most important to look under next."
"The results reported in our paper have been awaited for a long time and by many people," Warburton said. "There was friendly competition amongst us as to who will be the first to make a publishable measurement that either excludes or discovers New Physics, and I am proud that the ATLAS team won this race. I feel fortunate and privileged to have played a leading role in getting the analysis into a publishable form in a very short time." Warburton has since returned from Geneva to Montreal and his office at McGill University.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
