论文摘要
用于具有混乱和准常规区域混合空间的系统的准静态协议超出了绝热过程的标准范式。我们专注于由Bose-Hubbard Hamiltonian描述的多体原子系统，特别是由玻感位点组成的电路。我们考虑一个扫描过程：设备的旋转频率的缓慢变化（时间依赖于SAGNAC相）。相空间拓扑的参数变化意味着准静态极限是不可逆的。详细分析对于确定这种转移方案的结果及其效率至关重要。
Quasi-static protocols for systems that feature a mixed phase-space with both chaos and quasi-regular regions are beyond the standard paradigm of adiabatic processes. We focus on a many-body system of atoms that are described by the Bose-Hubbard Hamiltonian, specifically a circuit that consists of bosonic sites. We consider a sweep process: slow variation of the rotation frequency of the device (time dependent Sagnac phase). The parametric variation of phase-space topology implies that the quasi-static limit is irreversible. Detailed analysis is essential in order to determine the outcome of such transfer protocol, and its efficiency.
