标题： Dipolar magnetostirring protocol for three-well atomtronic circuits

摘要： 我们提出一种磁力搅拌协议，在环形系统上产生持续电流。 在该协议下，被限制在三井环形电路中的极化玻色子达到具有高平均循环性的状态。 我们用扩展的玻色-哈伯德哈密顿量来模拟该系统，并表明该协议可以在可调节参数范围内在原子电子电路中产生循环。 我们检查了该方案的性能和鲁棒性，特别是考虑不同的相互作用区域。 我们还提出了一种预测最佳协议参数的方法，这提高了协议的可扩展性，并使其能够应用于包含大量玻色子的系统。 这克服了计算限制，并为探索宏观量子现象铺平了道路。 显示英文摘要

摘要： 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.
