      abstract     = {Ultrasoft colloids typically do not spontaneously
                      crystallize, but rather vitrify, at high concentrations.
                      Combining in situ rheo–small-angle-neutron-scattering
                      experiments and numerical simulations we show that shear
                      facilitates crystallization of colloidal star polymers in
                      the vicinity of their glass transition. With increasing
                      shear rate well beyond rheological yielding, a transition is
                      found from an initial bcc-dominated structure to an
                      fcc-dominated one. This crystal-to-crystal transition is not
                      accompanied by intermediate melting but occurs via a sudden
                      reorganization of the crystal structure. Our results provide
                      a new avenue to tailor colloidal crystallization and the
                      crystal-to-crystal transition at the molecular level by
                      coupling softness and shear.},
