    "abstract": "Nontrivial steady flows have recently been found that capture the main\nstructures of the turbulent buffer layer. We study the effects of polymer\naddition on these \"exact coherent states\" (ECS) in plane Couette flow. Despite\nthe simplicity of the ECS flows, these effects closely mirror those observed\nexperimentally: Structures shift to larger length scales, wall-normal\nfluctuations are suppressed while streamwise ones are enhanced, and drag is\nreduced. The mechanism underlying these effects is elucidated. These results\nsuggest that the ECS are closely related to buffer layer turbulence.",
