Weakly coupled one-dimensional Mott insulators
We consider a model of one-dimensional Mott insulators coupled by a weak interchain tunneling t⊥. We first determine the single-particle Green's function of a single chain by exact field-theoretical methods and then take the tunneling into account by means of a random-phase approximation. In or...
