RENORMALIZATION GROUP APPROACH TO QUASI-ONE-DIMENSIONAL CONDUCTORS

摘要: We review the recent progress made in application of renormalization group method to interacting quasi-one-dimensional electron gas. From functional integral formulation partition function as expressed terms anticommuting Grassmann variables, effects single-electron interchain hopping on mechanisms propagation correlations leading long range ordering is analyzed full details for non-half-filled band case. Within a unified formalism, scaling features purely one-dimensional correlations, dimensionality crossover both single and composite particles, critical temperatures, responses functions are described.
