CERN Physicists Create Atoms of Pionic Helium Physicists from the ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) Collaboration at CERN have successfully synthesized and studied theoretically predicted but never before verified atoms of pionic helium. Their results mark the first time such spectroscopic measurements have been made on an …

Researchers Create Prototype of Microwave Quantum Radar A team of researchers from Austria, the U.S., the UK, and Italy has demonstrated a new technology called microwave quantum illumination that uses entangled microwave photons as a method of detection. Their prototype device is able to detect objects in noisy thermal environments …

New Measurements Show Evidence for Presence of Majorana Quasiparticles in Uranium Ditelluride An international team of physicists has used high-resolution microscopy tools to peer at the inner-workings of the recently-discovered heavy-fermion superconductor, uranium ditelluride (UTe2). The measurements reveal strong evidence that this material may be a natural home to an …

Scientists Develop Focus-Free Camera with Flat Lens A team of researchers from the University of Utah, Salt Lake City, and Oblate Optics, Inc. has created a camera that does not require focusing. The new flat lens could drastically reduce the weight, complexity and cost of cameras and other imaging systems, …

Dark issue is the mystical material that comprises approximately a quarter of deep space. There is solid indirect proof for its presence from dimensions of planetary primitive radiation, abnormalities in the radial reliance of stellar rotational contours and also gravitational lensing. In spite of its evidently essential duty in deep …

In a paper in the journal Physical Review Letters, an international team of physicists reports the most precise measurement ever made of the electric dipole moment of the neutron, a subatomic particle found in the nucleus of every atom except that of hydrogen. Their results show that the neutron has …

In 1947, American physicist Willis Lamb and his colleagues observed an incredibly small shift in the energy levels of the hydrogen atom as the atom’s electron and proton interacted with vacuum. Under traditional physics theories of the day, the Lamb shift shouldn’t have occurred. The ‘nothing’ of vacuum shouldn’t influence …

The strong force is one of the four fundamental forces of nature, which also include gravity, electromagnetism and the weak nuclear force. The strong force is responsible for binding together the protons and neutrons that form the nucleus of the atom, and thus the core of every atom that builds …
