Atomtronic Circuity
Abstract
Atomtronics refers to the ultracold atom analog of electronic components and circuits. This work was the first to develop and explore two key building blocks of atomtronic circuitry: a battery, which can serve to power atomtronic circuitry, and a transistor, which is the fundamental nonlinear building block that ultimately leads to the incredible breadth of the functional capability of circuits. The experimental demonstration of a battery showed that internal resistance is fundamental to battery action, and the resistance can be either positive or negative depending on the temperature of the atoms comprising the atomtronic current relative to parameters characterizing the batterys atom-trapping potential. The results of the atomtronic battery were used to demonstrate atom-(matterwave) current flow through an atomtronic transistor comprised of a triple-well potential having Source, Gate and Drain regions. A semi-classical analysis shows that current gain that is greater than unity is possible. The atom-current results are measured, and are in agreement with the semi-classical models. The demonstration of gain means that it is possible to conceive of atomtronic circuits operating on matterwaves as amplifiers, oscillators.
