原子电子超流电路准静态传输协议
Quasistatic transfer protocols for atomtronic superfluid circuits
摘要：
准静态协议的系统，具有混沌和准规则区域的混合相空间的功能超出了标准的绝热过程的范例。我们专注于一个多体系统的原子所描述的玻色哈伯德哈密顿量，特别是一个电路，由玻色子网站。我们考虑一个扫描过程：缓慢变化的旋转频率的设备（时间依赖Sagnac相位）。相空间拓扑的参数变化意味着准静态极限是不可逆的。为了确定这种转移协议的结果及其效率，必须进行详细的分析。
英文摘要：
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.
