      abstract     = {We investigate the dynamics of kinetically frozen block
                      copolymer micelles of different softness across a wide range
                      of particle concentrations, from the fluid to the onset of
                      glassy behavior, through a combination of rheology, dynamic
                      light scattering, and pulsed field gradient NMR
                      spectroscopy. We additionally perform Brownian dynamics
                      simulations based on an ultrasoft coarse-grained potential,
                      which are found to be in quantitative agreement with
                      experiments, capturing even the very details of dynamic
                      structure factors S(Q,t) on approaching the glass
                      transition. We provide evidence that for these systems the
                      Stokes-Einstein relation holds up to the glass transition;
                      given that it is violated for dense suspensions of hard
                      colloids, our findings suggest that its validity is an
                      intriguing signature of ultrasoft interactions.},
