Topological states in qubit arrays induced by density-dependent coupling
Andrei A. Stepanenko, Mark D. Lyubarov, Maxim A. Gorlach
Topological states of light open exciting possibilities in quantum photonics promising the topological protection of quantum entanglement. Here, we put forward an approach to reali…

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…
