Is your Supercomputer Stumped? There May Be a Quantum Solution

A new study led by a physicist at Berkeley Lab details how a quantum computing technique called “quantum annealing” can be used to solve problems relevant to fundamental questions in nuclear physics about the subatomic building blocks of all matter. It could also help answer other vexing questions in science and industry, too.

A Graphene Superconductor That Plays More Than One Tune

Researchers at Berkeley Lab have developed a graphene device that’s thinner than a human hair but has a depth of special traits. It easily switches from a superconducting material that conducts electricity without losing any energy, to an insulator that resists the flow of electric current, and back again to a superconductor – all with a simple flip of a switch.

Some Assembly Required: Scientists Piece Together the Largest U.S.-Based Dark Matter Experiment

Most of the remaining components needed to fully assemble an underground dark matter-search experiment called LUX-ZEPLIN (LZ) arrived at the project’s South Dakota home during a rush of deliveries in June. When complete, LZ will be the largest, most sensitive U.S.-based experiment yet that is designed to directly detect dark matter particles.

Simons Foundation Contributes $20M More to Observatory Exploring Early Universe

The Simons Observatory, a Berkeley Lab-involved project under construction in Chile’s Atacama Desert that will measure the properties of universe’s early light – the cosmic microwave background (CMB) – with extreme precision, has received a new commitment of $20 million from the Simons Foundation.

3 Sky Surveys Completed in Preparation for Dark Energy Spectroscopic Instrument

It took three sky surveys – conducted at telescopes in two continents, covering one-third of the visible sky, and requiring almost 1,000 observing nights – to prepare for a new project that will create the largest 3D map of the universe’s galaxies and glean new insights about the universe’s accelerating expansion.

Building a Better Electron Gun

The successful test of the LCLS-II electron gun marks the culmination of a Berkeley Lab R&D effort spanning more than a decade. The gun’s design was conceived in 2006 by John W. Staples, a retired Berkeley Lab physicist, and Fernando Sannibale, a senior scientist in Berkeley Lab’s Accelerator Technology and Applied Physics Division.

What if Dark Matter is Lighter? Report Calls for Small Experiments to Broaden the Hunt

Theorized dark matter particles haven’t yet shown up where scientists had expected them. So Berkeley Lab researchers are now designing new and nimble experiments that can look for dark matter in previously unexplored ranges of particle mass and energy, and using previously untested methods.

Berkeley Lab-Built Electron Gun Fires Up for LCLS-II X-Ray Laser Project

A new electron gun, designed and built at Berkeley Lab to supply electrons for a next-gen X-ray laser, fired its first electrons today. The X-ray laser is part of the LCLS-II project, which is an upgrade of SLAC National Accelerator Laboratory’s Linac Coherent Light Source X-ray laser.

‘A Day in the Light’ Videos Highlight How Scientists Use Light in Experiments

In recognition of the International Day of Light (@IDL2019) on May 16, the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) is highlighting how scientists use light in laboratory experiments. From nanolasers and X-ray beams to artificial photosynthesis and optical electronics, Berkeley Lab researchers tap into light’s many properties to drive a range of

A New Filter to Better Map the Dark Universe

To address messy measurements of the cosmic web that connects matter in the universe, researchers at Berkeley Lab developed a way to improve the accuracy and clarity of these measurements based on the stretching of the universe’s oldest light.
