Abstract
We propose a magnetostirring protocol to create persistent currents on an annular system. Under this protocol, polar bosons confined in a three-well ring circuit reach a state with high average circulation. We model the system with an extended Bose-Hubbard Hamiltonian and show that the protocol can create circulation in an atomtronic circuit for a range of tunable parameters. The performance and robustness of this scheme are examined, in particular considering different interaction regimes. We also present a method for predicting the optimal protocol parameters, which improves protocol's scalability and enables its application to systems with large numbers of bosons. This overcomes computational limitations and paves the way for exploring macroscopic quantum phenomena.

Reports on this Submission
Report
On Referee 2’s suggestion to transfer the paper to SciPost Physics Core: I understand the concern that the manuscript is quite technical in parts and relies on numerical optimisation, but I believe the protocol requires numerical simulation and analytical results would be very difficult to derive.
With this in mind, the manuscript is of relevance to the main SciPost Physics audience and can be published.
Recommendation
Publish (easily meets expectations and criteria for this Journal; among top 50%)
Report
Overall, the revisions to the manuscript implemented by the authors address the comments I raised in the previous round. I think that the current version of the paper meets the criteria and standards to be published in SciPost Physics.
Recommendation
Publish (meets expectations and criteria for this Journal)
