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 ...

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 ...

A new technique for measuring the electronic band structure of solid materials has been unveiled by physicists in Canada. The new method does not require the sample to be placed in a vacuum chamber ...

Phononic crystals are novel materials that offer exceptional control over phonons, sound and other mechanical waves. Taras Gorishnyy, Martin Maldovan, Chaitanya Ullal and Edwin Thomas report on a ...
