Dark Energy Survey Completes Six-year Mission

Scientists’ effort to map a portion of the sky in unprecedented detail is coming to an end, but their work to learn more about the expansion of the universe has just begun.

Sandia National Laboratories researchers are looking to shape the future of computing through a series of quantum information science projects. As part of the work, they will collaborate to design and develop a new quantum computer that will use trapped atomic ion technology. (Photo by Randy Montoya)

Quantum Computing Steps Further Ahead with New Projects at Sandia

Quantum computing steps further ahead with new projects at Sandia

SLAC/Stanford researchers have switched a material in and out of a topological state with novel electronic properties. The scientists controlled the switch with an invisible form of light, called terahertz radiation, which made layers of the material swing back and forth.

SLAC/Stanford Team Discovers New Way of Switching Exotic Properties On and Off in Topological Material

Ultrafast manipulation of material properties with light could stimulate the development of novel electronics, including quantum computers.

In the international Deep Underground Neutrino Experiment, hosted by Fermilab, a beam of neutrinos will be sent from Fermilab outside Chicago straight through Earth’s mantle to Sanford Lab in Lead, South Dakota. Fermilab recently finalized an agreement with construction firm Kiewit-Alberici Joint Venture to start pre-excavation work for the Long-Baseline Neutrino Facility, which will house the detectors.

Pre-excavation Work on LBNF/DUNE Begins in South Dakota

An international project to build the largest physics experiment ever constructed in the United States took a major step forward as a new phase of work has begun at the project’s South Dakota site.

The Relativistic Heavy Ion Collider (RHIC) is actually two accelerators in one. Beams of ions travel around its 2.4-mile-circumference rings in opposite directions at nearly the speed of light, coming into collision at points where the rings cross.

Startup Time for Ion Collisions Exploring the Phases of Nuclear Matter

19th year of operations at the Relativistic Heavy Ion Collider will continue search for critical point in transition from protons and neutrons to quark-gluon plasma.

Scientists at Argonne, the University of Chicago and Northwestern University have moved quantum optic networks a step closer to reality with their latest work on semiconducting nanoplatelets that act as tiny light switches.

Scientists Move Quantum Optic Networks a Step Closer to Reality

A crucial step has been achieved in understanding quantum optical behavior of semiconductor nanomaterials.

Yugang Zhang, Oleg Gang, Fang Lu, and Mingzhao Liu hold structural models of "nanowrappers" made of gold and silver and featuring holes in the corners. The scientists synthesized these hollow, porous nanostructures through a chemical reaction and characterized them using electron microscopy and optical spectroscopy capabilities at Brookhaven Lab's Center for Functional Nanomaterials.

Carrying and Releasing Nanoscale Cargo with "Nanowrappers"

Nanocubes with hollow interiors and surface openings whose shape, size, and location are precisely controlled could be used to load and unload materials for biomedical, catalysis, and optical sensing applications

The upgrade of the U.S. Department of Energy’s Advanced Photon Source at Argonne National Laboratory will make it between 100 and 1,000 times brighter than it is today.

Physicists Uncover New Competing State of Matter in Superconducting Material

A team of experimentalists at the U.S. Department of Energy’s Ames Laboratory and theoreticians at University of Alabama Birmingham discovered a remarkably long-lived new state of matter in an iron pnictide superconductor, which reveals a laser-induced formation of collective behaviors that compete with superconductivity.

Test accelerator under construction at Cornell will reuse energy, running beams through multi-pass magnets that help keep size and costs down.

Argonne researchers will use machine learning algorithms and artificial intelligence to improve simulations of internal combustion engines. Sibendu Som and his team are collaborating with Convergent Science and Parallel Works as part of this research, which is funded, in part, by the U.S. Department of Energy. The team will use the ALCF's Mira supercomputer as part of this engine modeling research. (Top image: Shutterstock / yucelyilmaz.)

Machine Learning Award Powers Argonne Leadership in Engine Design

As part of a partnership between the U.S. Department of Energy’s (DOE) Argonne National Laboratory and two companies, Convergent Science and Parallel Works, engine modelers are beginning to use machine learning algorithms and artificial intelligence to optimize their simulations.
