2-D Atoms Do the Twist

DOE/Lawrence Berkeley National Laboratory

In the study, scientists demonstrated, for the first time, an intrinsically rotating form of motion for the atoms in a crystal. The observations were on collective excitations of a single molecular layer of tungsten diselenide. Whether the rotation is clockwise or counter-clockwise depends on the wave's propagation direction. The observation means that there is a chirality associated with the phonon transport.

A day in the life of a cosmic-ray 'bookkeeper'

DOE/SLAC National Accelerator Laboratory

When he was growing up, Jonathan LeyVa thought he'd follow his passion for race cars and pick a profession in automotive engineering. Instead he's working on what will become one of the world's most sensitive searches for dark matter, the invisible substance that accounts for more than 85 percent of the mass of the universe.

Scientists finally find superconductivity in place they have been looking for decades

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

SLAC/Stanford scientists prove a well-known model of material behavior applies to high-temperature superconductors, giving them a new tool for understanding how these materials conduct electricity with no loss. Simulations suggest we might be able to toggle superconductivity on and off in certain materials by tweaking their chemistry so electrons hop from atom to atom in a particular pattern - as if hopping to the atom diagonally across the street rather than to the one next door.

Researchers home in on extremely rare nuclear process

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

A hypothetical nuclear process known as neutrinoless double beta decay ought to be among the least likely events in the universe. Now the international EXO-200 collaboration, which includes researchers from the Department of Energy's SLAC National Accelerator Laboratory, has determined just how unlikely it is.

How to get a particle detector on a plane

DOE/Lawrence Berkeley National Laboratory

Berkeley Lab is one of five sites around the globe that is building detector panels for an upgrade project that will improve the performance of a particle detector's inner tracking system -- including its resolution to take snapshots of particle collisions, its durability, and data-collection speed.

ESnet a key partner on project to build novel network research infrastructure

DOE/Lawrence Berkeley National Laboratory

Berkeley Lab's ESnet is one of five organizations leading an effort to create a nationwide research infrastructure that will enable the computer science and networking community to develop and test novel architectures that could yield a faster, more secure Internet.

New round of DOE awards bolsters quantum information science at SLAC

DOE/SLAC National Accelerator Laboratory

Researchers at the Department of Energy's SLAC National Accelerator Laboratory have received two DOE awards to explore how quantum information can be passed from one quantum device to another. The goal: develop ways to link quantum devices into quantum computing networks that are much more powerful than today's technology and into innovative photon detectors that could open up new areas of research, such as novel searches for dark matter.

How an Anti-Nuclear-Contamination Pill Could Also Help MRI Patients

DOE/Lawrence Berkeley National Laboratory

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) are studying how an anti-radiation-poisoning pill could help to protect people from the potential toxicity of gadolinium, a critical ingredient in widely used contrast dyes for MRI scans.
