      abstract     = {Self-assembled magnetocapillary microswimmers were
                      experimentally demonstrated recently. Here, we study the
                      motion of a magnetocapillary swimmer by means of a hybrid
                      lattice Boltzmann and discrete element method. Three
                      magnetic particles are placed at a fluid-fluid interface.
                      The particles deform the interface due to their weights,
                      leading thus to a capillary attraction force. At the same
                      time, the particles experience a repulsive magnetic
                      dipole-dipole force along with an upwards applied static
                      magnetic field. Through the competing of attractive
                      capillary and repulsive magnetic forces, a stable assembly
                      of the three magnetic particles is achieved. By applying an
                      oscillating horizontal magnetic field, the triplet
                      demonstrates a directed motion. We numerically investigate
                      the effect of frequency and direction of the magnetic field
                      on the motion of the swimmer and analyze the results
                      theoretically. In addition, we demonstrate a possible
                      application of magnetocapillary swimmers for cargo
                      transportation.},
