      abstract     = {Adhesion interactions mediated by multiple bond types are
                      relevant for many biological and soft matter systems,
                      including the adhesion of biological cells and
                      functionalized colloidal particles to various substrates. To
                      elucidate advantages and disadvantages of multiple bond
                      populations for the stability of heterogeneous adhesion
                      clusters of receptor-ligand pairs, a theoretical model for a
                      homogeneous parallel adhesion bond cluster under constant
                      loading is extended to several bond types. The stability of
                      the entire cluster can be tuned by changing densities of
                      different bond populations as well as their extensional
                      rigidity and binding properties. In particular, bond
                      extensional rigidities determine the distribution of total
                      load to be shared between different sub-populations. Under a
                      gradual increase of the total load, the rupture of a
                      heterogeneous adhesion cluster can be thought of as a
                      multistep discrete process, in which one of the bond
                      sub-populations ruptures first, followed by similar rupture
                      steps of other sub-populations or by immediate detachment of
                      the remaining cluster. This rupture behavior is
                      qualitatively independent of involved bond types, such as
                      slip and catch bonds. Interestingly, an optimal stability is
                      generally achieved when the total cluster load is shared
                      such that loads on distinct bond populations are equal to
                      their individual critical rupture forces. We also show that
                      cluster heterogeneity can drastically affect cluster
                      lifetime.},
