Fusion power is expected to be a sustainable energy source that emits no carbon dioxide during electricity generation. To achieve this, research is underway worldwide to confine high-temperature plasma using magnetic fields. To initiate a fusion reaction, high-energy particles or waves must be injected from outside to heat the plasma to extremely high temperatures.

Researchers at National Taiwan University (NTU) have reported the first experimental evidence of heat-current-driven transverse accumulation of electrons’ orbital angular momentum, a phenomenon known as the orbital Nernst effect. The study was recently published in Nature Communications.

An international research team led by Nobuhiro Yanai from the University of Tokyo and Michael R. Wasielewski from Northwestern University has created polarized radical pairs, molecules with unpaired electrons whose spins align, in metal–organic frameworks (MOFs), porous materials consisting of metal ions linked by organic molecules.

In a new study published in Measurement, researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences have developed a calibration method that combines machine vision with interferometry. This method separates a mirror’s fixed internal offset from changes in the test path alignment.

Researchers have developed a new approach that can precisely count from zero to more than 9,000 individual photons. The advance opens new possibilities for studying quantum light at large scales and making precise optical measurements.

The universe’s dominance by ordinary matter is compelling evidence that matter and antimatter are not perfect reflections of each other. However, known differences do not explain the scale of this imbalance, leaving open the possibility that unknown physics is responsible. A new analysis of meson decays, conducted by the LHCb collaboration, has narrowed the scope […]

Scientists from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences have directly observed liquid-like, glass-like and crystal-like phonon behaviors coexisting in a crystalline solid—the layered superionic conductor AgCrSe₂.

First, one person stands up, followed by their neighbors, one after another, until a wave sweeps through the stadium. Atoms within a material move in a similar way: rather than remaining completely still in their positions, they vibrate together around their respective positions. In physics, these collective lattice vibrations are known as “phonons.” Some of […]
