Light derails electrons through graphene

The way electrons flow in a material determines its electronic properties. For example, when a voltage is sustained across a conducting material, electrons start flowing, generating an electrical current. These electrons ...

Why pulsars shine bright: A half-century-old mystery solved

When Jocelyn Bell first observed the emissions of a pulsar in 1967, the rhythmic pulses of radio waves so confounded astronomers that they considered whether the light could be signals sent by an alien civilization.

A superconducting diode without an external magnetic field

Superconductors are the key to lossless current flow. However, the realization of superconducting diodes has only recently become an important topic of fundamental research. An international research team involving the theoretical ...
