摘要: We investigate a system of one-dimensional Hubbard chains interacting fermions coupled by interchain hopping. Using generalization the dynamical mean-field theory we study deconfinement transition from Mott insulator to metal and crossover between Luttinger Fermi liquid phases. One-particle properties, local spin response, optical conductivity are calculated. Possible applications organic conductors discussed.
