One of the simplest and most beautiful naturally occurring patterns can be observed when light is shined through a pair of slightly misaligned periodic structures. This phenomenon, known as the moiré ...

Coherent diffractive imaging (CDI) is a state-of-the-art imaging technique that uses diffraction from a coherent beam of light or electrons to reconstruct an image of a specimen without the need for ...

When Louis de Broglie postulated that we need to ‘associate a periodic phenomenon with any isolated portion of matter or energy’, he predicted that these new ideas would ‘solve almost all the problems ...
