Query: Dissipative Preparation of Antiferromagnetic Order in the Fermi-Hubbard
  Model   The Fermi-Hubbard model is one of the key models of condensed matter physics,
which holds a potential for explaining the mystery of high-temperature
superconductivity. Recent progress in ultracold atoms in optical lattices has
paved the way to studying the model's phase diagram using the tools of quantum
simulation, which emerged as a promising alternative to the numerical
calculations plagued by the infamous sign problem. However, the temperatures
achieved using elaborate laser cooling protocols so far have been too high to
show the appearance of antiferromagnetic and superconducting quantum phases
directly. In this work, we demonstrate that using the machinery of dissipative
quantum state engineering, one can efficiently prepare antiferromagnetic order
in present-day experiments with ultracold fermions. The core of the approach is
to add incoherent laser scattering in such a way that the antiferromagnetic
state emerges as the dark state of the driven-dissipative dynamics. In order to
elucidate the development of the antiferromagnetic order we employ two
complementary techniques: Monte Carlo wave function simulations for small
systems and a recently proposed variational method for open quantum systems,
operating in the thermodynamic limit. The controlled dissipation channels
described in this work are straightforward to add to already existing
experimental setups.
