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 ...

Transient grating (TG) spectroscopy is a time-resolved technique that belongs to the broader family of nonlinear four-wave mixing methods. It is best understood as the time-domain analogue of ...

Information processing in today’s computers is done almost exclusively by charges (electric currents). Photons, albeit they are ideal for information transmission, never became a mainstream technology ...
