First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the Massachusetts Institute of Technology (MIT) have performed a daring experiment using ...

Using a highly coherent positronium beam, the researchers observed clear diffraction patterns after transmission through a graphene film, confirming its wave-like behavior. One of the discoveries that ...

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new way to structure light in custom, repeatable, three-dimensional patterns, ...
