Query: Dissipative preparation of fractional Chern insulators   We report on the numerically exact simulation of the dissipative dynamics
governed by quantum master equations that feature fractional quantum Hall
states as unique steady states. In particular, for the paradigmatic Hofstadter
model, we show how Laughlin states can be to good approximation prepared in a
dissipative fashion from arbitrary initial states by simply pumping strongly
interacting bosons into the lowest Chern band of the corresponding
single-particle spectrum. While pure (up to topological degeneracy) steady
states are only reached in the low-flux limit or for extended hopping range, we
observe a certain robustness regarding the overlap of the steady state with
fractional quantum Hall states for experimentally well-controlled flux
densities. This may be seen as an encouraging step towards addressing the
long-standing challenge of preparing strongly correlated topological phases in
quantum simulators.
