Nonequilibrium thermodynamical inequivalence of quantum stress-energy and spin tensors

It is shown that different pairs of stress-energy and spin tensors of quantum relativistic fields related by a pseudo-gauge transformation, i.e., differing by a divergence, imply different mean values of physical quantities in thermodynamical nonequilibrium situations. Most notably, transport coeffi...
