      abstract     = {Recent theoretical work has shown that the competition
                      between coherent unitary dynamics and stochastic
                      measurements, performed by the environment, along wave
                      function trajectories can give rise to transitions in the
                      entanglement scaling. In this work, complementary to these
                      previous studies, we analyze a situation where the role of
                      Hamiltonian and dissipative dynamics is reversed. We
                      consider an engineered dissipation, which stabilizes an
                      entangled phase of a quantum spin−12 chain, while
                      competing single-particle or interacting Hamiltonian
                      dynamics induce a disentangled phase. Focusing on the
                      single-particle unitary dynamics, we find that the system
                      undergoes an entanglement transition from a logarithmic
                      growth with system size to an area law when the competition
                      ratio between the unitary evolution and the nonunitary
                      dynamics increases. We evidence that the transition
                      manifests itself in state-dependent observables at a finite
                      competition ratio for Hamiltonian and measurement dynamics.
                      On the other hand, it is absent in trajectory-averaged
                      steady-state dynamics, governed by a Lindblad master
                      equation: although purely dissipative dynamics stabilizes an
                      entangled state, for any nonvanishing Hamiltonian
                      contribution the system ends up irremediably in a disordered
                      phase. In addition, a single trajectory analysis reveals
                      that the distribution of the entanglement entropy
                      constitutes an efficient indicator of the transition.
                      Complementarily, we explore the competition of the
                      dissipation with coherent dynamics generated by an
                      interacting Hamiltonian, and demonstrate that the
                      entanglement transition also occurs in this second model.
                      Our results suggest that this type of transition takes place
                      for a broader class of Hamiltonians, underlining its
                      robustness in monitored open quantum many-body systems.},
