Query: Emergent light crystal from frustration and pump engineering   We demonstrate how pump engineering drives the emergence of
frustration-induced quasi-long-range order in a low-dimensional photonic cavity
array. We consider a Lieb chain of nonlinear cavities as described by the
Bose-Hubbard model and featuring a photonic flat band in the single-particle
spectrum. Incoherent pumping of the Lieb lattice leads to a photonic
density-wave which manifests an algebraic decay of correlations with twice the
period of the lattice unit cell. This work opens up new directions for the
emergence of strongly-correlated phases in quantum optical frustrated systems
through pump design.
