      abstract     = {The effective force between two parallel DNA molecules is
                      calculated as a function of their mutual separation for
                      different valencies of counterion and salt ions and
                      different salt concentrations. Computer simulations of the
                      primitive model are used and the shape of the DNA molecules
                      is accurately modeled using different geometrical shapes. We
                      find that multivalent ions induce a significant attraction
                      between the DNA molecules whose strength can be tuned by the
                      averaged valency of the ions. The physical origin of the
                      attraction is traced back either to electrostatics or to
                      entropic contributions. For multivalent counterions and
                      monovalent salt ions, we find a salt-enhanced repulsion
                      effect: the force is first attractive but gets repulsive
                      with increasing salt concentration. Furthermore, we show
                      that the multivalent-ion-induced attraction does not
                      necessarily correlate with DNA overcharging.},
