Abstract: (SciPost Fundation)
We classify all possible allowed constitutive relations of relativisticfluids in a statistical mechanical limit using the Schwinger-Keldysh effectiveaction for hydrodynamics. We find that microscopic unitarity enforces genuinelynew constraints on the allowed transport coefficients that are invisible in theclassical hydrodynamic description; they are not implied by the second law orthe Onsager relations. We term these conditions Schwinger-Keldysh positivityand provide explicit examples of the various allowed terms.Note:
