Physicists have long regarded plasma turbulence as unruly behavior that can limit the performance of fusion experiments. But new findings by researchers associated with the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and the Department of Astrophysical Sciences at Princeton University indicate that turbulent swirls of plasma could benefit one of the two major branches of such research.
Post-doctoral researchers, Karim Essafi, Owen Benton and Ludovic Jaubert in the Theory of Quantum Matter Unit at the Okinawa Institute of Science and Technology Graduate University (OIST) are on a quest to find out as much as they can about unusual states of matter called spin liquids and if these spin liquids could generate advances in the field of physics. The results could lead to the development of quantum computing, which require an exploration of new materials to become a reality.

Better thermometers might be possible as a result of a discovery at the National Institute of Standards and Technology (NIST), where physicists have found a way to calibrate temperature measurements by monitoring the tiny motions of a nanomechanical system that are governed by the often counterintuitive rules of quantum mechanics.
The challenge of high temperature superconductivity in the cuprates triggers innovative scientific investigations. A key question remains the complexity of the phase diagram. As temperature and doping change, these materials switch between superconducting, metallic, and insulating phases, as well as other more exotic phases, such as the elusive pseudogap.
The two major pillars of modern physics are relativity theory and quantum mechanics, and several new phenomena have been discovered with their combination. For example, a major outcome of the quantum field theory is the Unruh effect, which acts as a critical tool to study a number of phenomena, including particles that are thermally emitted from cosmological horizons and black holes.
John Zasadzinski, a professor of physics at Illinois Institute of Technology (IIT), will present “Superconductivity in accelerator and particle physics” at 4 p.m. Tuesday, March 22, in Moulton Hall, room 214. The talk is part of the Spring 2016 Physics Colloquium.
Using some of the largest supercomputers available, physics researchers from the University of Illinois at Urbana-Champaign have produced one of the largest simulations ever to help explain one of physics most daunting problems.
Dark matter is all around us. Though no one has ever seen it, and no one knows what it really is, indisputable physical calculations state that approximately 27% of the universe is dark matter. Only five % is the matter of which all known materials consist; from the smallest ant to the largest galaxy.
A research team led by the University of Leeds has observed for the first time how HIV and Ebola viruses attach to cells to spread infection.
Scientists from the National Physical Laboratory (NPL) have demonstrated the ability to detect the presence or absence of individual electrons with unprecedented accuracy.
Big Bang neutrinos are believed to be everywhere in the universe but have never been seen. As the oldest known witnesses or relics of the early universe, these subatomic particles could shed new light on the birth of the cosmos if scientists could pin them down. That's a tall order since these ghostly particles can speed through planets as if they were empty space.
Bazinga! University of Cincinnati theoretical physicists are about to report on a controversial discovery that they say contradicts the work of researchers over the decades.
Since the 17th century, science was intrigued by the nature of light. Isaac Newton was certain that it consists of a stream of particles. His contemporary Christiaan Huygens, however, argued that light is a wave. Modern quantum physics says that both were right.
The optical chip developed at INRS by Prof. Roberto Morandotti’s team overcomes a number of obstacles in the development of quantum computers, which are expected to revolutionize information processing. The international research team has demonstrated that on-chip quantum frequency combs can be used to simultaneously generate multiphoton entangled quantum bit (qubit) states.
In a presentation today at the Smithers Apex’s 4th Annual Quantum Dots Forum in Newport Beach, California, Dr. Nathan Stott, Quantum Materials Corp. Director of Materials, outlined the Company's goals for increasing the efficiency and commercial viability of solar energy production through the integration of quantum dots into thin-film solar cells.
