Nanoscale currents improve understanding of quantum phenomena

Besides charge, subatomic particles like electrons also carry a property called spin, which is responsible for magnetism. Novel proposals to use spin to store information have emerged in recent years with the promise to be ...

Lasers trigger magnetism in atomically thin quantum materials

Researchers have discovered that light—in the form of a laser—can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electrons. These subatomic particles have an ...

Quantum physics sets a speed limit to electronics

How fast can electronics be? When computer chips work with ever shorter signals and time intervals, at some point they come up against physical limits. The quantum-mechanical processes that enable the generation of electric ...

Getting quantum dots to stop blinking

Quantum dots, discovered in the 1990s, have a wide range of applications and are perhaps best known for producing vivid colors in some high-end televisions. But for some potential uses, such as tracking biochemical pathways ...
