Edge states of photon pairs in cavity arrays with spatially modulated nonlinearity
Mark Lyubarov, Alexander Poddubny
We study theoretically an extended Bose-Hubbard model with the spatially modulated interaction strength, describing a one-dimensional array of tunneling-coupled nonlinear cavities.…

Exceptional points for photon pairs bound by nonlinear dissipation in cavity arrays
Mark Lyubarov, Alexander Poddubny
We study theoretically the dissipative Bose-Hubbard model describing array of tunneling-coupled cavities with non-conservative photon-photon interaction. Our calculation of the com…
