      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 139 fb$^{-1}$ of $pp$ collisions at
                      $\sqrt{s}=13$ TeV, 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. In the singlet
                      model, the limits allow $m_T > 1.27$ TeV and $m_B > 1.20$
                      TeV. In the doublet model, allowed masses are $m_T > 1.46$
                      TeV and $m_B >1.32$ TeV. In the case of 100\% branching
                      ratio for $T\rightarrow Zt$ and 100\% branching ratio for
                      $B\rightarrow Zb$, the limits allow $m_T > 1.60$ TeV and
                      $m_B > 1.42$ TeV, respectively.},
