Cold connection: A Josephson junction in an ultracold 2D Fermi gas. (Courtesy: AG Moritz) Researchers in Germany have created a new platform for studying quantum phenomena by realizing a Josephson ...

Physicists in the US are the first to have created a locally-gated p-n junction in graphene, which is a 2D sheet of carbon just one atom thick. The charge density in the device is controlled by ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...

The field of condensed matter physics explores the macroscopic and microscopic properties of matter. Condensed Matter physicists study how matter arises from a large number of interacting atoms and ...

The story so far: Quantum mechanics says that particles can sometimes cross barriers they don’t have the energy to climb, like boring through a mountain instead of scaling it first. This process, ...
