Frustration-induced quasi-long-range order in a photonic system — •Matteo Biondi, Gianni Blatter, and Sebastian Schmidt — Institut für Theoretische Physik, Wolfgang-Pauli-Str. 27 8093 Zürich Switzerland
We investigate the interplay of geometric frustration and interactions in a nonequilibrium photonic lattice system exhibiting a photonic flat band as described by the driven-dissipative Bose-Hubbard model. We propose how to engineer quasi-long-range order in a quasi one-dimensional frustrated system by pumping the photonic lattice incoherently. Using a filter qubit
to modulate the bandwidth of the pump, we demonstrate how to obtain a quasi-pure density-wave state of photons characterized by a polynomial decay of density-density correlations. We provide analytic results together with finite-size simulations of the Lindblad master equation using exact diagonalization and propose a state-of-the-art photonic realization of our system within cavity QED.
