Two, six, many - physicists observe the emergence of collective behaviour

Phase transitions describe dramatic changes in properties of a macroscopic system - like the transition from a liquid to a gas. Starting from individual ultracold atoms, physicists were able to observe the emergence of such a transition with an increasing number of particles.

Researchers find a better way to design metal alloys

System uses machine learning to analyze boundaries between crystal grains, allowing for selection of desired properties in a new metal.

Researchers create MRI-like technique for imaging magnetic waves in ultrathin magnets

The MRI system made by the researchers makes use of a special lattice defect in the crystal structure of diamonds. This defect - known as nitrogen-vacancy centre - enables high-resolution imaging of the magnetic structure of a sample.
