Researchers uncover mystery of optical wave trapped in three-dimensional micro or nanoparticles.
Tunneling spectroscopy confirms exotic superconducting state in iron-based superconductor.
A kind of metamaterial that has been beyond the reach of existing technologies so far.
The interaction between electrons and light is the most fundamental interaction in physics. Scientists from Goethe University Frankfurt performed an experiment in which they observed the Kapitza-Dirac effect for the first time in full temporal resolution.
First postulated almost nine decades ago, the Kapitza–Dirac effect is a quantum mechanical effect consisting of the diffraction of matter by a standing wave of light. In its original description, the effect is time-independent.
Researchers at EPFL and the Max Planck Institute have incorporated nonlinear optical phenomena into a transmission electron microscope (TEM), which uses electrons for imaging instead of light.
Nonlinear optics, the study of unpredictable light behavior in materials, has applications in various fields, from laser development to quantum information science. Integrating nonlinear optics into a TEM enables complex light interactions on a small chip, allowing for the miniaturization of devices in applications such as optical signal processing, telecommunications, sensing, and spectroscopy.
🤔 Alef Aeronautics’ drivable flying car takes its maiden flight in a city field. The development team has introduced the Alef Model A, the dubbed production version of the drivable flying car that has vertical take-off and landing capabilities. On February 19th, 2025, its test model takes off, even flying over another vehicle. In a LinkedIn post, Alef Aeronautics CEO Jim Dukhovny writes that the video showcasing the flight is ‘the first documented, verifiable flight of a flying car (an actual car, with vertical takeoff, non-tethered).’
*This is an old, but new post. Some people have posted about the same car years ago.
