Probing hydrodynamic crossovers with dissipation-assisted operator evolution
N. S. Srivatsa, Oliver Lunt, Tibor Rakovszky +1
Using artificial dissipation to tame entanglement growth, we chart the emergence of diffusion in a generic interacting lattice model for varying U(1) charge densities. We follow th…

Sub-ballistic growth of Rényi entropies due to diffusion
Tibor Rakovszky, Frank Pollmann, C. W. von Keyserlingk
We investigate the dynamics of quantum entanglement after a global quench and uncover a qualitative difference between the behavior of the von Neumann entropy and higher Rényi entr…
