Physicists create superatom

13.01.2015

The motto “United we are strong“ is also valid in the quantum world.

Under appropriate conditions, a cloud of several hundred atoms can behave like a single atom, virtually developing super-power. Upon excitation with an ultraviolet laser into highly excited states, the atoms start to interact with each other.

This interaction can be made so strong that exactly one atom of the cloud is excited and the excitation of two or more atoms is suppressed. Because every atom in the cloud can be the chosen one, quantum mechanics tell us that in such a situation, all possibilities are realized simultaneously.

The atoms are therefore connected with each other and constitute a single object – a superatom – with a hundred times enhanced excitation probability as compared to a single atom.

The groups of Prof. Herwig Ott and Prof. Michael Fleischhauer from the University of Kaiserslautern have shown how such a superatom can be created und under which conditions the above mentioned properties can be observed.

Superatoms are not only fascinating physical objects, they bear also great potential for the future application in quantum information processing.

The study has been published in the highly renowned journal “Nature Physics”. DOI:10.1038/nphys3214

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
