Lecture in English. Transport phenomena are ubiquitous in nature and technology – from enormous flows of neutrinos emanating from an exploding supernova to tiny electrical currents in the chip of your smartphone. Transport is said to be far-from equilibrium if it goes beyond a small perturbation above the equilibrium and eludes simple linear descriptions like the Ohm’s law. Transport goes quantum whenever the motion of charge carries can no longer be described by laws of classical physics – either due to interference effects manifest when the carries are tightly confined at tiny length scales, as in quantum point contacts, or thanks to strong quantum inter-particle correlations, as in superconductors. In general, theoretically describing the far-from-equilibrium quantum transport is, perhaps
