Query: Localization and delocalization dynamics of photons in linearly coupled
  cavity arrays   Localization and delocalization of two photons in an array of cavities are
examined. Role of entanglement and relative phase of the initial state in the
occurrence of localization or delocalization during time evolution is
elucidated.
