@article{Yamamoto2020RectificationIN, title={Rectification in nonequilibrium steady states of open many-body systems}, author={Kazuki Yamamoto and Yuto Ashida and Norio Kawakami}, journal={arXiv: Quantum Gases}, year={2020} }

We study how translationally invariant couplings of many-body systems and nonequilibrium baths can be used to rectify particle currents. We propose novel 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 nonreciprocal current. Remarkably, we show that rectification can…
