Layered room temperature pleural magnets are promising for advanced spintronics
ARPE (a) measured and calculated (b) Fermi surface of rb1-Δv2te2o. The blue and red colors in (b) indicate reverse spin polarization. This is also evidenced by the spin-resolved alpine spectra shown in (c) and (d). Credit: Zhang et al Traditionally, magnetic materials have been divided into two main categories: ferromagnets and antiferromagnets. However, over the past few years, physicists have…

Chirality induces huge charge rectification of superconductors
Optical images of devices (#1) of thin film κ-NCS (a) before laser manufacturing and (b). Credit: Physics Review Study (2025). doi:10.1103/physrevresearch.7.023056 Recent studies have revealed that electrons passing through chiral molecules exhibit significant spin-polarized light, a phenomenon known as chirality-induced spin selectivity. This effect is attributed to the non-critical bond between electron motion and spins within chiral structures, but quantifies…

The atlas enters under the hood of the Higgs mechanism
Display of candidate events for the production of two W+ bosons via vector boson scattering, followed by a collapse into two muons and two muon neutrinos. Muons are represented by the red lines of the inner detector and Muon spectrometer, with two jets represented by a yellow cone. The direction of missing lateral energy associated with the two neutrinos is…

Maximum entanglement sheds new light on the creation of particles
When an energetic quark or gluon is knocked freely during a proton-proton collision, this free “parton” first generates a shower of other partons, then “fragmented” to form hadrons (h), such as kons (k), pion (π), and protons (p). The higher the energy of the first quark or gluon, the higher the number of hadrons. If the hadron entropy is equal…

Scientists discover better when it comes to time domain spectroscopy of terahertz
A close-up of a simplified experimental setup of Terahertz Time-Domain spectroscopy, demonstrated by Hayazawa and his team. Credit: Riken Advanced Photonics Center A simple adjustment to a normal setup is all that is needed to enhance spectroscopic techniques using waves in the terahertz region for samples, Riken physicists discovered. Findings can be found in the Journal Applied Physics Letters. Developing…

New experimental half weight limit for elusive neutrinos
Installation of the internal electrode system for the main spectrometer of catrin. Credit: Markus Breig, kit Scientists seeking to discover the elusive mass of neutrinos, the small “ghost particles” that can solve some of the universe’s biggest mysteries, announced new limits on how much they can weigh, halving previous estimates. Since the existence of neutrinos was proposed almost a century…

Cross-sectional area variation as a key factor for pressure wave attenuation in hilarious flows: a theoretical analysis.
Credit: International Journal by Multiphase Flow (2025). doi:10.1016/j.ijmultiphaseflow.2025.105138 Pressure waves propagating through the liquid containing bubbles in the tube experience considerable decay. Researchers at Tsukuba University have derived an equation explaining this phenomenon, showing that variations in the tube cross-sectional area contribute to wave attenuation, beyond the viscosity and compressibility of the liquid. Their analysis reveals that the rate of…
