    "abstract": "Starting from stationary bifurcations in Couette-Dean flow, we compute\nnontrivial stationary solutions in inertialess viscoelastic circular Couette\nflow. These solutions are strongly localized vortex pairs, exist at arbitrarily\nlarge wavelengths, and show hysteresis in the Weissenberg number, similar to\nexperimentally observed ``diwhirl\u0027\u0027 patterns. Based on the computed velocity\nand stress fields, we elucidate a heuristic, fully nonlinear mechanism for\nthese flows. We propose that these localized, fully nonlinear structures\ncomprise fundamental building blocks for complex spatiotemporal dynamics in the\nflow of elastic liquids.",
