When we think about a diamond, we often think about a material whose value comes from its perfection. In my research, however, I am interested in something almost opposite: the tiny imperfections inside diamonds. These atomic-scale defects can give diamonds new optical and electronic properties, and some of them can serve as quantum systems.

The challenge is learning how to control these defects without disturbing the others.

A famous quantum effect can finally be predicted in real materials

Scientists have developed a powerful new way to calculate the Kondo effect, a strange quantum phenomenon that appears when magnetic atoms are embedded in metals. Instead of relying on simplified models, the method uses the real atomic and electronic structures of materials, allow
