It is known that a semiclassical analysis is not always adequate for atomtronics devices, but that a fully quantum analysis is often necessary to make reliable predictions. While small numbers of atoms at a small number of sites are tractable using the density matrix, a fully quantum analysis is often not straightforward as the system becomes larger. We show that the fully quantum positive-P representation is then a viable calculational tool. We postulate an atomtronic phase gate consisting of… Expand

Mesoscopic Dynamical Differences from Quantum State Preparation in a Bose-Hubbard Trimer.
Differences in the preparation of a centrally evacuated trimer can lead to readily observable differences in the subsequent dynamics which increase with system size, and these differences can be detected by the simple measurements of atomic number. Expand
Quantum behaviour of open pumped and damped Bose-Hubbard trimers
We propose and analyse analogs of optical cavities for atoms using three-well inline Bose-Hubbard models with pumping and losses. With one well pumped and one damped, we find that both the mean-fieldExpand

We analyze the quantum state of fermionic carriers in a transport channel attached to a particle reservoir. The analysis is done from first principles by considering microscopic models of theExpand
Control of tunneling in a triple-well system: an atomtronic switching device
We study a model of bosons confined to three coupled wells. The model describes interactions between bosons, tunneling of bosons between adjacent wells, and the effect of an external field. WeExpand

Challenges and constraints of dynamically emerged source and sink in atomtronic circuits: From closed-system to open-system approaches
This work considers dynamically emerged local potentials as controllable source and sink for bosonic atoms in cold-atom systems and investigates what types of system-environment coupling can help bring bosons into a dynamically emerged sink. Expand
