      abstract     = {Dispersions of particles with short-range attractive and
                      long-range repulsive interactions exhibit rich equilibrium
                      microstructures and a complex phase behavior. We present
                      theoretical and simulation results for structural and, in
                      particular, short-time diffusion properties of a colloidal
                      model system with such interactions, both in the
                      dispersed-fluid and equilibrium-cluster phase regions. The
                      particle interactions are described by a generalized
                      Lennard-Jones-Yukawa pair potential. For the
                      theoretical-analytical description, we apply the hybrid
                      Beenakker–Mazur pairwise additivity (BM-PA) scheme. The
                      static structure factor input to this scheme is calculated
                      self-consistently using the Zerah-Hansen integral equation
                      theory approach. In the simulations, a hybrid simulation
                      method is adopted, combing molecular dynamics simulations of
                      colloids with the multiparticle collision dynamics approach
                      for the fluid, which fully captures hydrodynamic
                      interactions. The comparison of our theoretical and
                      simulation results confirms the high accuracy of the BM-PA
                      scheme for dispersed-fluid phase systems. For particle
                      attraction strengths exceeding a critical value, our
                      simulations yield an equilibrium cluster phase. Calculations
                      of the mean lifetime of the appearing clusters and the
                      comparison with the analytical prediction of the
                      dissociation time of an isolated particle pair reveal
                      quantitative differences pointing to the importance of
                      many-particle hydrodynamic interactions for the cluster
                      dynamics. The cluster lifetime in the equilibrium-cluster
                      phase increases far stronger with increasing attraction
                      strength than that in the dispersed-fluid phase. Moreover,
                      significant changes in the cluster shapes are observed in
                      the course of time. Hence, an equilibrium-cluster dispersion
                      cannot be treated dynamically as a system of permanent rigid
                      bodies.},
