(Phys.org)—Researchers from the University of Leipzig have found that doping very small flakes of graphite with water, then allowing it to dry, results in a material that behaves very much like a superconductor. The team, ...
For months, Anthony West could hardly believe what he and his colleagues were seeing in the lab -- or the only explanation for the unexpected phenomena that seemed to make sense.

In a proof-of-principle experiment, researchers at UNSW Australia have demonstrated that a small group of individual atoms placed very precisely in silicon can act as a quantum simulator, mimicking nature - in this case, ...

Polarisability determines the force with which an inhomogeneous external electric field acts on the ions of an ion beam. However, it can be quite tricky to obtain accurate values for this force. Now, two German theoretical ...
