A deeper understanding of the emergence of out-of-equilibrium statistical physics, and enhanced ability to control quantum many-body systems with single-site precision, can lead to a new era of quantum transport exploration. In order to reach that, we focus on a nonequilibrium scenario in which two nonintegrable systems prepared in different states are locally and non-extensively coupled to each other. We show the emergence of steady-like currents which are well defined and typical. We identify their origin to be from a prethermalization mechanism. We then discuss the experimental realization of these findings on a state-of-the-art experimental setup.
