Atomtronic Transistors & Circuits

As an analog of electronics, atomtronics provides a framework for making use of ultracold atoms in practical applications involving sensing and quantum information processing tasks. For the same reason that the semiconductor transistor is so ubiquitous and important in electronics, so is the atomtronic matterwave transistor pivotal to atomtronic circuitry. Atomtronic circuits are fundamentally many-bodied quantum systems operating in an open-systems regime. That is to say, even the simplest atomtronic circuits present challenges to a full understanding of their behavior.

This work begins with a review of our experimental work on a triple-well atomtronic transistor and then provides insight into the underlying principles of transistor action leading, in particular, to matterwave gain and how that gain might be used in some simple but meaningful applications such as a gyroscope for inertial navigation.
