I will discuss the dynamics of entanglement in quantum systems evolving unitarily from a far-from-equilibrium initial state, focusing how it is affected by the diffusive transport of conserved quantities such as energy or charge. I will show that such transport leads to qualitative differences between different measures of entanglement; in particular between different Renyi entropies. This result is relevant for ongoing cold atom experiments and constitutes a previously unappreciated feature of the thermalization process in interacting quantum systems. I will describe various approaches to understand this phenomenon and discuss minimal models where it can be observed numerically.
