Phys. Rev. Lett. 99, 186401 (2007) [4 pages]Mott-Insulating and Glassy Phases of Polaritons in 1D Arrays of Coupled CavitiesReceived 8 May 2007; published 29 October 2007 By means of analytical and numerical methods we analyze the phase diagram of polaritons in one-dimensional coupled cavities. We locate the phase boundary, discuss the behavior of the polariton compressibility and visibility fringes across the critical point, and find a nontrivial scaling of the phase boundary as a function of the number of atoms inside each cavity. We also predict the emergence of a polaritonic glassy phase when the number of atoms fluctuates from cavity to cavity. © 2007 The American Physical Society URL:
