When quantum electrodynamics, the quantum field theory of electrons and photons, was being developed after World War II, one of the major challenges for theorists was calculating a value for the Lamb ...
Electron microscopy uses a beam of electrons to illuminate a sample and achieve much higher spatial resolution than light microscopy. Transmission electron microscopy generates an image of the ...
Scientists have controlled hybrid quantum states in helium using intense ultraviolet lasers, opening new paths in quantum ...
An international group of researchers from the University of Freiburg's Institute of Physics has created and directly ...

Scanning electron microscopy is a general type of electron microscopy that generates a topological image of a sample using a beam of electrons to achieve much higher spatial resolution than light ...
For thousands of years, thinkers argued about whether light is made of particles or waves. At the beginning of the 20th ...
Electrons, those fundamental particles that orbit atomic nuclei, are central to electromagnetism and chemical processes. Ever ...
However, if an atom is in the beam of a very intense laser, the energy levels shift. Hybrid electron-photon states are created, known as "dressed states." These occur at laser intensities in the ...
Scientists are exploring 2D materials — sheets just one atom thick — with unique and promising electronic properties. When two of these sheets are layered at specific angles, they can exhibit ...
