While superfluid circuits using ultracold boson-like atoms already exist, the Dartmouth circuit is the first to use ultracold atoms that act as fermions. The circuit operates on the isotope lithium-6.

Electron billiards in nanoscale circuits Date: October 24, 2010 Source: Technische Universitaet Muenchen Summary: In solar cells, solar radiation boosts electrons to higher energy states, thereby ...

They’ve essentially toggled the electron highway signs with an external magnetic field. This elegant control over band asymmetry might lead to low-power, high-speed data storage based on ...

At the heart of these devices are active components, or components of the circuit that electronically control electron flow, like semiconductors.
