Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

A new theoretical study led by researchers at the University of Chicago and Argonne National Laboratory has identified the ...

Some of the X-ray radiation circulating in the cavity is allowed to escape downstream, providing a beam of monochromatic and coherent X-ray pulses. They have called their system X-ray Free-Electron ...

An incident plane-wave laser is tuned by a diffractive optical part like grating or prism, and then being transformed into a tilted pulse laser. This tilted pulse is then focused by a sOAP mirror. A ...
