Title : Pushing Atoms Instead of Electrons: Everything You Learned about Circuits Still Helps
Abstract : Atomtronics is an emerging interdisciplinary field that is creating new devices and circuits where ultracold atoms, often in the superfluid state, have a role analogous to that of electrons in electronics. After giving a brief overview of some experimental neutral atom-circuit results, I will show how these results can be described by lumped-element models analogous to those used in electronics. Resistance, capacitance and inductance can be defined for neutral-atom circuits, and they are analogous to the Sharvin resistance (in the non-superfluid case), quantum capacitance, and kinetic inductance, respectively, in electronic circuits. In the superfluid case, resistance must include different channels of dissipation, and thus is not just a Sharvin resistance.
