An answer to a quantum-physical question provided by the algorithm Melvin has uncovered a hidden link between quantum experiments and the mathematical field of Graph Theory. Researchers from the Austrian Academy of Sciences and the University of Vienna found the deep connection between experimental quantum physics and this mathematical theory in the study of Melvin's unusual solutions, which lies beyond human intuition.

A new cloaking technology has been developed at TU Wien: a special kind of material is irradiated from above in such a way that another beam of light can pass completely uninhibited. The material is irradiated with a specially designed pattern, the wave from the left can pass through the object completely unperturbed.

Using new computer algorithms, it is possible to adjust specific properties of three-dimensional objects, such as the sounds they produce or how stable they are. The thickness of a piece of metal made into different animal shapes - including a giraffe and a fish - is adjusted by using a computer algorithm in such a way that a specific sound spectrum is exhibited when the objects are struck.
