In a new study, scientists have observed long-lived excitons in a topological material, opening intriguing new research directions for optoelectronics and quantum computing. Excitons are charge-neutral quasiparticles created when light is absorbed by a semiconductor. Consisting of an excited electron coupled to a lower-energy electron vacancy or hole, an exciton is typically short-lived, surviving only […]
To understand Earth’s changing climate, scientists often turn to science-based computer simulations. Researchers strive to make these Earth system models as accurate as possible. Factors such as wind currents, air quality, and weather patterns all play a role. But current modeling has often overlooked one important activity: agriculture. The post Modeling Agriculture Matters for Carbon […]
Accurate and fast calculation of heat flow (heat transport) due to fluctuations and turbulence in plasmas is an important issue in elucidating the physical mechanisms of fusion reactors and in predicting and controlling their performance. The post Researchers Utilize Supercomputer to Develop a High-precision Mathematical Model to Predict Plasma Flows appeared first on HPCwire.
Two new Department of Energy-sponsored telescopes, the Dark Energy Spectroscopic Instrument (DESI) and the Vera C. Rubin Observatory, will map cosmic structure in unprecedented detail. At Argonne and Lawrence Berkeley national laboratories, teams have developed a pair of the world’s most powerful cosmological simulation codes and are ready to translate the telescopes’ tsunami of observational […]
Feng Pan is a postdoctoral researcher in Jennifer Dionne’s lab at Stanford University. He makes metamaterials to manipulate light for quantum information storage. Image credit: D-lab/Stanford University. Scientist Feng Pan creates materials with sculptural features that manipulate light not for their visual effects, but to encode information. The post Feng Pan Sculpts Ultrathin Materials for […]
March 22, 2023 — A new leaf has turned in scientists’ hunt for developing cutting-edge materials used in organic light-emitting diode (OLED) TV’s, touchscreens, and more. The advance involves the polaron, a quasiparticle consisting of an electron and its surrounding distortions of atoms in a crystal lattice. The post New Simulation Reveals Secrets of Exotic […]
Researchers have discovered a way to “translate” quantum information between different kinds of quantum technologies, with significant implications for quantum computing, communication, and networking. The post New Experiment Translates Quantum Information Between Tech in Important Step for Quantum Internet appeared first on HPCwire.
The rise of artificial intelligence (AI) and a branch of AI called machine learning, which focuses on the use of data and algorithms to imitate the way that humans learn, is rapidly changing the way data-intensive scientific discovery is being done. The post Science Beyond Siri: A Team of Educators and Computer Scientists Take on […]
An innovative food and nutrition project is uniquely combining artificial intelligence (AI) and social enterprise business models to help address the challenge of food deserts in the U.S. These are places across the country where supermarkets are more than one mile away in urban neighborhoods or 10 miles away in rural communities. Residents in these […]
Researchers at the University of Oxford have recently created a quantum memory within a trapped-ion quantum network node. Their unique memory design, introduced in a paper in Physical Review Letters, has been found to be extremely robust, meaning that it could store information for long periods of time despite ongoing network activity. The post A […]
