Abstract
I will show how the notion of entropy production emerges from basic properties of quantum field theory. For this purpose I will introduce a general non-equilibrium effective field theory of slow degrees of freedom of a quantum many-body system. The key ingredients are unitarity of the microscopic theory, and a Z_2 symmetry, which is associated to the presence of local equilibrium. As an example, I will show how the entropy current emerges from our recent effective field theory formulation of hydrodynamics.
