Smart atomic cloud solves Heisenberg's observation problem

One of the most fundamental principles of physics, "Quantum Back Action", has been challenged by researchers from the Niels Bohr Institute, which has used laser light to link a vibrating membrane with cesium atoms.

Iron secrets behind superconductors unlocked

Due to magnetism iron should - theoretically - be a poor superconductor. Nevertheless certain ironbased materials possess fine superconducting properties. Why? Because the five unbound electrons found in iron...
