报告摘要：

Transport phenomena in superfluid systems have been extensively studied for decades, yet open questions remain especially in strongly interacting systems and in far-from-equilibrium settings. In this talk, I will focus on a cold-atom setup of two reservoirs connected by a mesoscopic channel, i.e., a quantum point contact. When the reservoirs are in the superfluid phase, a chemical potential bias induces a large and nonlinear particle current, characteristic of superfluid behaviours. In the first part, I will show experiments revealing a surprising nature of this current by measuring the concurrent entropy transport and production. In the second part, I will talk about a new direction of engineering local particle dissipation inside the channel and observing its effect on the transport between superfluids.
