      abstract     = {A search for the pair-production of vector-like quarks
                      optimized for decays into a Z boson and a third-generation
                      Standard Model quark is presented, using the full Run 2
                      dataset corresponding to 139fb−1 of pp collisions at
                      s=13TeV, collected in 2015–2018 with the ATLAS detector at
                      the Large Hadron Collider. The targeted final state is
                      characterized by the presence of a Z boson with high
                      transverse momentum, reconstructed from a pair of
                      same-flavour leptons with opposite-sign charges, as well as
                      by the presence of b-tagged jets and
                      high-transverse-momentum large-radius jets reconstructed
                      from calibrated smaller-radius jets. Events with exactly two
                      or at least three leptons are used, which are further
                      categorized by the presence of boosted W, Z, and Higgs
                      bosons and top quarks. The categorization is performed using
                      a neural-network-based boosted object tagger to enhance the
                      sensitivity to signal relative to the background. No
                      significant excess above the background expectation is
                      observed and exclusion limits at $95\%$ confidence level are
                      set on the masses of the vector-like partners T and B of the
                      top and bottom quarks, respectively. The limits depend on
                      the branching ratio configurations and, in the case of
                      $100\%$ branching ratio for T→Zt and $100\%$ branching
                      ratio for B→Zb, this search sets the most stringent limits
                      to date, allowing mT>1.60TeV and mB>1.42TeV, respectively.},
