论文摘要
我们研究了许多粒子系统和非平衡浴的翻译不变耦合如何用于整流颗粒电流，为此，我们认为我们认为最小的设置以实现一维开放式费米尼式系统的非平衡稳态中的浴诱导的电流。我们首先分析了与非逆局Lindblad操作员相关的耗散动力学，并确定一类Lindblad操作员足以获得单向电流。我们表明，只要lindblad operator是相互的，只要倒置对称性与微观哈密顿量的时间反转对称性被损坏时，通常会发生单向粒子传输。我们根据分析方法和数值方法（包括Rashba旋转轨道耦合和Zeeman磁场）来证明这种机制。
We study how translationally invariant couplings of many-particle systems and nonequilibrium baths can be used to rectify particle currents, for which we consider minimal setups to realize bath-induced currents in nonequilibrium steady states of one-dimensional open fermionic systems. We first analyze dissipative dynamics associated with a nonreciprocal Lindblad operator and identify a class of Lindblad operators that are sufficient to acquire a unidirectional current. We show that unidirectional particle transport can in general occur when a Lindblad operator is reciprocal provided that the inversion symmetry and the time-reversal symmetry of the microscopic Hamiltonian are broken. We demonstrate this mechanism on the basis of both analytical and numerical approaches including the Rashba spin-orbit coupling and the Zeeman magnetic field.
