Researchers Provide Unambiguous Demonstration of Coherent Transport of Phonons

We all learn in high school science about the dual nature of light - that it exists as both waves and quantum particles called photons.

Black Holes May Have Imprinted a Clear Signature in Radio Waves

A new study from Tel Aviv University reveals that black holes, formed from the first stars in our universe, heated the gas throughout space later than previously thought.

Graphene Nanoribbons Act Like Quantum Dots

Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature – a property known as ballistic transport.

Defects in Diamond Hold Potential as Quantum Sensors of High Pressure Phenomena

New research shows that a remarkable defect in synthetic diamond produced by chemical vapor deposition allows researchers to measure, witness, and potentially manipulate electrons in a manner that could lead to new “quantum technology” for information processing. The study is published in the January 31, 2014, issue of Physical Review Letters.

Optical Rogue Waves Observed in a Test Tube

Random processes in nature often underlie a so-called normal distribution that enables reliable estimation for the appearance of extreme statistical events. Meteorological systems are an exception to this rule, with extreme events appearing at a much higher rate than could be predicted from long-term observation at much lower magnitude.

Researchers win NSERC John C Polanyi Award for Characterizing Antihydrogen Atom

A Canadian team including UBC physicist Walter Hardy and TRIUMF researchers have won the NSERC John C Polanyi Award for their work in creating, capturing and characterizing the antihydrogen atom. The team also includes Dr. Fujiwara of University of Calgary (also the spokesperson for the ALPHA-Canada team) and Dr. Michael Hayden of Simon Fraser University, both alumni of UBC Physics & Astronomy.

Heavy Solitons Most Likely Quantum Equivalent of Smoke Rings

The same physics that gives tornadoes their ferocious stability lies at the heart of new University of Washington research, and could lead to a better understanding of nuclear dynamics in studying fission, superconductors and the workings of neutron stars.

Nano-Heat Engine with Just a Single Ion

Scientists at Johannes Gutenberg University Mainz (JGU) and the University of Erlangen-Nuremberg are working on a heat engine that consists of just a single ion. Such a nano-heat engine could be far more efficient than, for example, a car engine or a coal-fired power plant. A usual heat engine transforms heat into utilizable mechanical energy with the corresponding efficiency of an Otto engine amounting to only about 25 percent, for instance.

Particle Physics Theory Describes Behaviour of Excitons in Two Layers of Graphene

Belgian scientists have used a particle physics theory to describe the behaviour of particle-like entities, referred to as excitons, in two layers of graphene, a one-carbon-atom-thick honeycomb crystal. In a paper published in EPJ B, Michael Sarrazin from the University of Namur, and Fabrice Petit from the Belgian Ceramic Research Centre in Mons, studied the behaviour of excitons in a bilayer of graphene through an analogy with excitons evolving in two abstract parallel worlds, described with equations typically used in high-energy particle physics.

Accelerator Physicists Pump Liquid Helium to Chill RHIC's 1,740 Superconducting Magnets to Near Absolute Zero

If you think it's been cold outside this winter, that's nothing compared to the deep freeze setting in at the Relativistic Heavy Ion Collider (RHIC), the early-universe-recreating "atom smasher" at the U.S. Department of Energy's Brookhaven National Laboratory. Brookhaven's accelerator physicists have begun pumping liquid helium into RHIC's 1,740 superconducting magnets to chill them to near absolute zero (-273 degrees Celsius—the coldest anything can get) in preparation for the collider's next physics run.

Scientists Unravel How Topological Insulators Work

Topological insulators are the key to future spintronics technologies. EPFL scientists have unraveled how these strange materials work, overcoming one of the biggest obstacles on the way to next-generation applications.

Quantum Dots Enable Creation of Light with High Degree of Linear Polarization

By emitting photons from a quantum dot at the top of a micropyramid, researchers at Linköping University are creating a polarized light source for such things as energy-saving computer screens and wiretap-proof communications.

Jolting Complex Materials with Energy Bursts Can Help Study High-Temperature Superconductivity

Jolting complex materials with bursts of energy from rapid-fire lasers can help scientists learn why some of these materials exhibit useful properties such as high-temperature superconductivity, a team led by SLAC and Stanford researchers has reported.

Researchers Complete Computer Simulations of Early Stages of Planet Formation Around Binary Stars

Luke Skywalker's home planet Tatooine would have formed far from its current location in the Star Wars universe, a new University of Bristol study into its real world counterparts, observed by the Kepler space telescope, suggests.

Simple Way to Slow Down Polar Molecules Offers New Opportunities in Quantum Information Processing

Compared with our breath, passenger planes move at a pretty leisurely pace. On the average, nitrogen molecules, for example, travel at a speed of more than 1,700 kilometres per hour at room temperature, or almost one-and-a-half times the speed of sound. This means the particles are much too fast for many experiments, and also some conceivable applications.
