MPQ/Caltech scientists demonstrate mechanical analogue to an optical laser with single ions

26-Aug-2009

For decades there has been interest in phonon lasers that emit quanta of vibrational energy - so called phonons - instead of light. In solids, because of the short wavelength, the implementation of such a device would make it possible to achieve unprecedented resolution in imaging techniques like ...

Theoretical physicists of the Max Planck Institute of Quantum Optics reveal limitations of Density Functional Theory using Quantum Information Theory tools

24-Aug-2009

The electric and magnetic properties of solids are impossible to calculate exactly: The complex interactions of the many electrons which underly these phenomena cannot be computed even by the most powerful classical computers. Here, the central task is to determine the ground state of the ...

Tracking down new active agents for cancer or malaria treatment could soon become easier - thanks to a computer program with which researchers from the Max Planck Institute of Molecular Physiology in Dortmund aim to facilitate the search for suitable pharmaceutical substances. The program, which ...

Two new construction manuals are now available for the world's smallest lamps. Based on these protocols, scientists from the Max Planck Institute of Colloids and Interfaces have tailor-made nanoparticles that can be used as position lights on cell proteins and, possibly in the future as well, as ...

It has a beautiful, but also an unpleasant side: crystallization determines the shape of precious stones, but also causes the lime scale in washing machines. How this comes about, has been known for a long time - or has it? Scientists at the Max Planck Institute of Colloids and Interfaces are now ...

Scientists watch on the atomic level how individual molecules recognize each other

04-May-2007

The body is an almost perfect machine. For it to function properly, each individual component, that is each molecule, must reliably fulfill its specific function. Each molecule must thus "recognize" other molecules and work with them. A team of researchers from the Max Planck Institute for Solid ...
