In the photonic synthetic dimension, the coupling of internal degrees of freedom of photons, such as frequency, spatial mode, and orbital angular momentum, generates extra dimensions in addition to ...

Researchers at Lund University, Sweden, have grown single continuous GaAs nanowires consisting of segments of pure wurtzite and zincblende phases. Using photoluminescence spectroscopy, they found that ...

Researchers have devised a straightforward method to probe the band geometry using ultracold atoms in an optical lattice. MPQ/LMU scientists devise new interferometer to probe the geometry of band ...

Most of the time, cooking is a matter of following a recipe - combine specific amounts of specific ingredients in the right way and the predictable outcome is that you'll wind up with a tasty meal.

Despite a deep understanding of the properties of individual atoms -- the 'ingredients' that make up a crystal -- scientists found that, when they are combined they often display new, unanticipated ...
