Article describes cause of chirping that signals loss of heat from fusion reactions.
An international team of researchers present new mathematical equations that with minimal increase in computational complexity allow for accurate and experimentally testable predictions.
Nuclear fusion, the process that powers our sun, happens when nuclear reactions between light elements produce heavier ones. It's also happening -- at a smaller scale -- in a Colorado State University laboratory. Using a compact but powerful laser to heat arrays of ordered nanowires, CSU scientists and collaborators have demonstrated micro-scale nuclear fusion in the lab. They have achieved record-setting efficiency for the generation of neutrons -- chargeless sub-atomic particles resulting from the fusion process.
University of British Columbia researchers have found a new system that could help yield 'warmer' quantum technologies.
A team of physicists from the Hong Kong University of Science and Technology and Peking University reported the observation of an SPT phase for ultracold atoms using atomic quantum simulation. This work opens the way to expanding the scope of SPT physics with ultracold atoms and studying non-equilibrium quantum dynamics in these exotic systems.
Scientists at Rice University and the Indian Institute of Science, Bangalore, have discovered a method to make atomically flat gallium that shows promise for nanoscale electronics.
The phenomenon of metastability -- when a system is in a state that is stable but not the one of least energy -- is widely observed in nature and technology. Yet, many aspects underlying the mechanisms governing the behaviour and dynamics of such systems remain unexplored. Physicists at ETH Zurich have now demonstrated a promising platform for studying metastability on a fundamental level, using an exquisitely well controlled gas consisting of a few ten thousands of atoms.
Scientists at Tokyo Institute of Technology (Tokyo Tech) have developed a technique for analyzing structural and electronic fluctuations on the single-molecule scale across the metal-molecule interface in an organic electronic device. This technique provides information that cannot be obtained using the conventional method, and it has important implications for devices such as organic solar cells.
An team of physicists from Innsbruck and Hannover has for the first time observed so-called roton quasiparticles in a quantum gas. Empirically introduced by Landau to explain the bizarre properties of superfluid liquid Helium, these quasiparticles reflect an 'energy softening' in the system as precursor of a crystallization instability. The new work published in Nature Physics demonstrate similar phenomena in the quantum-gas phase thanks to magnetic interactions, paving the way for a novel understanding of paradigmatic states of quantum fluids, such as supersolids.
JILA scientists have invented a new imaging technique that produces rapid, precise measurements of quantum behavior in an atomic clock in the form of near-instant visual art.
