Description

Recently, theoretical studies have advertised electromagnetic resonator (photon) arrays in circuit QED, coherently coupled to artificial atoms (e.g., superconducting qubits) as a new venue for constructing quantum simulators for strongly correlated states of matter [1]. In particular, we describe the Mott-Superfluid transition of light in these systems and build a correspondence with the Bose- Hubbard model [2]. We also explore the possibilities of breaking time-reversal symmetry in such interacting photon systems [3] allowing to realize novel topological phases. Finally, we discuss the effect of interactions on two-dimensional topological (electron) band insulators [4].
