Polarized electrons are electrons in which spins have a "preferred" orientation or are preferentially oriented in a specific direction. The realization of these electrons has notable implications for physics research, as ...
Physicists and material scientists have been trying to metallize hydrogen for many decades, but they have not yet succeeded. In 1968, British physicist Neil Ashcroft predicted that atomic metallic hydrogen would be a high-temperature ...
For several decades, physicists have known that light can be described simultaneously as a wave and a particle. This fascinating 'duality' of light is due to the classical and quantum nature of electromagnetic excitations, ...
While researchers have conducted countless studies exploring the interaction between light waves and bound electron systems, the quantum interactions between free electrons and light have only recently become a topic of interest ...
From common soot to precious diamonds, carbon is familiar in many guises, but there have been little more than glimpses of carbon in the liquid form. Researchers at the FERMI Free Electron Laser (FEL) source have now not ...
(Phys.org)—Photosynthesis – the ubiquitous yet remarkable process by which most plants, algae, and cyanobacteria convert light energy into chemical energy – provides the atmospheric oxygen and organic compounds fundamental ...
(PhysOrg.com) -- Double-core-hole (DCH) states – in which two electrons are ejected from their positions, creating vacancies – occurring at different atomic sites are very sensitive to the chemical environment of ...
(PhysOrg.com) -- The idea of generating hydrogen from salt water has often been claimed to work effectively. However, the systems proposed so far generally require a much greater energy input than the energy they produce, ...
Giant-impact driven redox processes in the atmosphere and magma ocean may have played crucial roles during the evolution of the Earth. However, the absence of rock records from the time or era makes it challenging to understand ...
Particle accelerators hold great potential for semiconductor applications, medical imaging and therapy, and research in materials, energy and medicine. But conventional accelerators require plenty of elbow room—kilometers—making ...
