AI enhances plasma plume analysis

16 septembre

In a published in the journal npj Computational Materials, Oak Ridge National Laboratory scientists developed a deep learning model—a type of artificial intelligence that mimics human brain function—to analyze high-speed videos of plasma plumes during a process called pulsed laser deposition, or (…)

Deep design produces ’butterfly’ phase mask for light-sheet fluorescence microscopy

16 septembre

Researchers have introduced a solution to the problem of light-sheet fluorescence microscopy : novel illumination beams designed based on deep learning using a trainable phase mask. Their study eliminates the need for sophisticated optical design tools, allowing optimization to be directly (…)

Tunable nonlinear Hall effect observed at room temperature in tellurium

16 septembre

A research team has discovered significant nonlinear Hall and wireless rectification effects at room temperature in elemental semiconductor tellurium (Te). Their research is published in Nature Communications.

New strategy for simulating nonadiabatic dynamics of molecules at metal surfaces

16 septembre

A research team has proposed a novel approach to accurately describe electron transfer mediated nonadiabatic dynamics of molecules at metal surfaces. Their works were published in Physical Review Letters.

Energy-saving computing with magnetic whirls

16 septembre

Researchers at Johannes Gutenberg University Mainz (JGU) have managed to enhance the framework of Brownian reservoir computing by recording and transferring hand gestures to the system that then used skyrmions to detect these individual gestures.

Research team uses terahertz pulses of light to shed light on superconducting disorder

16 septembre

A team of researchers from the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg, Germany, and Brookhaven National Laboratory in the United States has demonstrated a new way to study disorder in superconductors using terahertz pulses of light.

Theoretical physicists develop method to model a central theory of quantum gravity in the laboratory

16 septembre

Gravity is no longer a mystery to physicists—at least when it comes to large distances. Thanks to science, we can calculate the orbits of planets, predict tides, and send rockets into space with precision. However, the theoretical description of gravity reaches its limits at the level of the (…)

Multifunctional phosphor developed for white LED lighting and optical thermometry

13 septembre

In the realm of lighting and temperature measurement, advancements in material science are paving the way for significant improvements in technology and safety. Traditional methods, which combine yellow phosphors with blue chips in LEDs, have limitations such as inadequate red light components (…)

Researchers simulate novel metal-filtered VCSEL modal control

13 septembre

A study led by researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences revealed a novel metal-dielectric film mode filter structure that can flexibly regulate transverse modes in vertical-cavity surface-emitting lasers (VCSELs), which (…)

Findings from experimental setup demonstrate potential for compact and portable nuclear clocks

13 septembre

Scientists use atomic clocks to measure the "second," the smallest standard unit of time, with great precision. These clocks use natural oscillations of electrons in atoms, similar to how pendulums work in old grandfather clocks. The quest for an even more precise timekeeper led to the (…)
