Physicists at the Swiss Nanoscience Institute and the University of Basel have succeeded in measuring the very weak van der Waals forces between individual atoms for the first time. To do this, they fixed individual noble gas atoms within a molecular network and determined the interactions with a single xenon atom that they had positioned at the tip of an atomic force microscope. As expected, the forces varied according to the distance between the two atoms; but, in some cases, the forces were several times larger than theoretically calculated. These findings are reported by the international team of researchers in «Nature Communications». more...

Predictions from quantum physics have been confirmed by countless experiments, but no one has yet detected the quantum physical effect of entanglement directly with the naked eye. This should now be possible thanks to an experiment proposed by a team around theoretical physicist Nicolas Sangouard at the University of Basel. The experiment might pave the way for new applications in quantum physics. more...

Scientists at the Swiss Nanoscience Institute and the Department of Physics at the University of Basel have developed a new method that has enabled them to image magnetic fields on the nanometer scale at temperatures close to absolute zero for the first time. They used spins in special diamonds as quantum sensors in a new kind of microscope to generate images of magnetic fields in superconductors with unrivalled precision. In this way the researchers were able to perform measurements that permit new insights in solid state physics, as they report in “Nature Nanotechnology”. more...

The atom without properties

The microscopic world is governed by the rules of quantum mechanics, where the properties of a particle can be completely undetermined and yet strongly correlated with those of other particles. A team of theoretical and experimental physicists from the University of Basel has observed these so-called Bell correlations for the first time between hundreds of atoms. Their findings are published today in the scientific journal «Science». more...

The John Templeton Foundation is a US based entity that serves as a philanthropic catalyst for discoveries related e.g. to a deeper understanding of the nature of reality within the realm of quantum theory, cosmology, astronomy, or chemistry. The Foundation has recently awarded a generous grant for a project entitled «Is the human eye able to see entanglement?» which will be led by SNSF Professor Nicolas Sangouard.

Reliability of quantum mechanical simulations tested

Various approximations have to be used in the numerical solution of the many-electron Schroedinger equation and it was frequently not quite clear how strongly these approximations would affect the accuracy of the final result obtained by electronic structure simulation codes. In an open worldwide collaborative effort the main developers of electronic structure codes have joined forces to compare and validate their codes. The results of the most accurate codes were recently published in «Science» and showed very good agreement. Among these codes was the BigDFT code developed in the group of Prof. S. Goedecker. more...
