Reconstructing the phase of a field from intensity measurements is an old and ubiquitous challenge, known as the phase retrieval problem 1,2,3. It has found numerous applications spanning from ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

Electrons travelling through two slits and a single slit. (Courtesy: Herman Batelaan/New Journal of Physics) Physicists in the US and Canada say that they have done the best job yet of realizing ...
