      abstract     = {The phase behavior of supersoft spheres is explored using
                      solutions of ultralow cross-linked
                      poly(N-isopropylacrylamide)-based microgels as a model
                      system. For these microgels, the effects of the electric
                      charges on their surfaces can be neglected and therefore
                      only the role of softness on the phase behavior is
                      investigated. The samples show a liquid-to-crystal
                      transition at higher volume fraction with respect to both
                      hard spheres and stiffer microgels. Furthermore, stable body
                      centered cubic (bcc) crystals are observed in addition to
                      the expected face centered cubic (fcc) crystals. Small-angle
                      x-ray and neutron scattering with contrast variation allow
                      the characterization of both the microgel-to-microgel
                      distance and the architecture of single microgels in crowded
                      solutions. The measurements reveal that the stable bcc
                      crystals depend on the interplay between the collapse and
                      the interpenetration of the external shell of the ultralow
                      cross-linked microgels.},
