Analytic approximations to the phase diagram of the Jaynes-Cummings-Hubbard model
Analytic approximations to the phase diagram of the Jaynes-Cummings-Hubbard model
We discuss analytic approximations to the ground-state phase diagram of the homogeneous Jaynes-Cummings-Hubbard (JCH) Hamiltonian with general short-range hopping. The JCH model describes, e.g., radial phonon excitations of a linear chain of ions coupled to an external laser field tuned to the red motional sideband with Coulomb-mediated hopping or an …
