Apr. 26, 2023 By superimposing two laser fields of different strengths and frequency, the electron emission of metals can be measured and controlled precisely to a few attoseconds. Physicists have shown that this ...
Apr. 24, 2024 Researchers discovered that light can cause evaporation of water from a surface without the need for heat. This 'photomolecular effect' could be important for understanding climate change ...
Jan. 4, 2023 Researchers have found a way to create much stronger interactions between photons and electrons, in the process producing a hundredfold increase in the emission of light from a phenomenon called ...
Jan. 18, 2024 A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, ...
Nov. 7, 2023 A team of researchers has built a prototype microscope that does not rely on backscattered radiation, instead uses passive detection of thermally excited evanescent waves. They have examined ...
Mar. 10, 2025 Researchers have experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum ...
May 17, 2024 Scientists have the first direct evidence that the powerful magnetic fields created in off-center collisions of atomic nuclei induce an electric current in 'deconfined' nuclear matter. The ...
Mar. 20, 2023 The development of new information and communication technologies poses new challenges to scientists and industry. Designing new quantum materials -- whose exceptional properties stem from quantum ...
Mar. 13, 2025 With today's data rates of only a few hundred megabytes per second, access to digital information remains relatively slow. Initial experiments have already shown a promising new strategy: ...
Aug. 14, 2023 Medical imaging via X-rays, CT scans, MRIs and ultrasounds provide health-care professionals with unique perspectives and a better understanding of what's happening inside a patient's body. ...
