Jaynes-Cummings Lattice. (a) The schematic of a one-dimensional JC lattice with qubit-cavity coupling g and photon hopping rate J. (b) The energy spectrum of a single JC model for detuning \(\Delta =0\), where \(\vert 0,\downarrow \rangle\) is the ground state and \(\vert n,\pm \rangle\) (\(n\geq1\), integer) are the lowest excited states. (c) The single particle density matrix \(\rho _{1}(1,3)\) vs hopping rate J and detuning \(\Delta\) for a \(N=4\) lattice at unit filling. Here we let \(g=1\), and all parameters are in dimensionless units58.
