First came electronics, the processing of information in terms of the charge of electrons flowing through circuits. Later a new form of tronics, spintronics, was invented to exploit the magnetic properties of electrons. Over the past decade or so still another information modality, atomtronics, has been under development, one employing not electrons but neutral atoms as the vehicle for information. The latest chapter in this development is the demonstration of a rudimentary atomtronic analog of capacitance.
The new results, undertaken by a group led by Wendell Hill at the Joint Quantum Institute (JQI), are published in the journal Nature Scientific Reports.
