How light can vaporize water without the need for heat

23 avril

It’s the most fundamental of processes—the evaporation of water from the surfaces of oceans and lakes, the burning off of fog in the morning sun, and the drying of briny ponds that leaves solid salt behind. Evaporation is all around us, and humans have been observing it and making use of it (…)

Spintronics research shows material’s magnetic properties can predict how a spin current changes with temperature

23 avril

Spintronics is a field garnering immense attention for its range of potential advantages for conventional electronics. These include reducing power consumption, high-speed operation, non-volatility, and the potential for new functionalities.

CMS Collaboration observes new all-heavy quark structures

23 avril

For over a decade, the CMS Collaboration, a large team of researchers based at different institutes worldwide, has been analyzing data collected at the Compact Muon Solenoid, a general-purpose particle detector at CERN’s Large Hadron Collider (LHC). This large-scale international scientific (…)

The big quantum chill : Scientists modify common lab refrigerator to cool faster with less energy

23 avril

By modifying a refrigerator commonly used in both research and industry, researchers at the National Institute of Standards and Technology (NIST) have drastically reduced the time and energy required to cool materials to within a few degrees above absolute zero.

Novel method could explore gluon saturation at the future electron-ion collider

23 avril

The U.S. nuclear physics community is preparing to build the electron–ion collider (EIC), a flagship facility for probing the properties of matter and the strong nuclear force that holds matter together. The EIC will allow scientists to study how nucleons (protons and neutrons) arise from the (…)

Record electron temperatures for a small-scale, sheared-flow-stabilized Z-pinch fusion device achieved

23 avril

In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature of the core of the sun. Zap Energy’s unique (…)

Hunting for the elusive : IceCube observes seven potential tau neutrinos

23 avril

Researchers at the IceCube Neutrino Observatory in Antarctica have found seven signals that could potentially indicate tau neutrinos—which are famously hard to detect—from astrophysical objects.

Manipulating the geometry of the ’electron universe’ in magnets

23 avril

Researchers at Tohoku University and the Japan Atomic Energy Agency have developed fundamental experiments and theories to manipulate the geometry of the "electron universe," which describes the structure of electronic quantum states in a manner mathematically similar to the actual (…)

Study shines light on properties and promise of hexagonal boron nitride, used in electronic and photonics technologies

23 avril

Single-photon emitters (SPEs) are akin to microscopic lightbulbs that emit only one photon (a quantum of light) at a time. These tiny structures hold immense importance for the development of quantum technology, particularly in applications such as secure communications and high-resolution (…)

Tunable quantum anomalous Hall effects in van der Waals heterostructures

23 avril

The quantum anomalous Hall effect (QAHE) has unique advantages in topotronic applications, but realizing the QAHE with tunable magnetic and topological properties for building functional devices is still a key scientific challenge. Through first-principles calculations, researchers have (…)
