Scientists used high magnetic fields and low temperatures to study crystals of URu2–xFexSi2. Using these conditions, they explored an intriguing state of matter called the "hidden order phase" that exhibits emergent behavior. Emergent behavior occurs when the whole is greater than the sum of its parts, meaning the whole has exciting properties that its parts do not possess; it is an important concept in philosophy, the brain and theories of life. This data provide strict constraints on theories of emergent behavior.

Analogous to the unique spectral fingerprint of any atom or molecule, researchers have measured the spectrum of optical excitations in monolayer tungsten diselenide (WSe2), which is a member of a new family of ultrathin semiconductors that are just one atomic layer thick.

Researchers discover that Sr1-yMn1-zSb2 (y,z < 0.1) is a so-called Weyl material that holds great promise for building devices that require far less power.

This finding sheds light on the role of quasiparticle mass enhancement near a quantum critical point in one of the leading families of high-temperature superconductors.

Discovery could help scientists better understand exotic behaviors of electrons.

Scientists discovered how to tune the optical properties of atomically-thin semiconductors, which will aid the design of future microscopic light sensors.

This week at the lab, we're preparing a home for a new magnet that will give more scientists access to some of the highest magnetic fields in the world.

The new Duplex Magnet, slated for completion this fall at the Pulsed Field Facility in Los Alamos, New Mexico, will reach fields up to 80 teslas, although it will most often run at 75 teslas to extend its lifetime. Like the other instruments available at the Pulsed Field Facility, the Duplex will generate these incredibly high fields for just a fraction of a second — still ample time for physicists to get valuable data.

But unlike the facility’s other magnets, the Duplex features two coils that will be powered by separate circuits and capacitors. This design helps operators better manage the temperature and stress the instrument is subjected to and allows for flexibility in future improvements.

The Duplex will be located near the facility’s primary workhorse, the 65 Tesla Multi-Shot Magnet. Featuring the same 15-millimeter bore for inserting experiments, it will enable more scientists to do cutting-edge experiments in these extreme fields.
