摘要：

Scaling properties of a self-dual field-theoretical model, describing two weakly coupled spinless Luttinger chains, are studied. A crossover to a sine-Gordon massive phase, with strongly developed two-particle interchain correlations, is described. It is argued that, in a wide range of the in-chain interaction, renormalization of the interchain hopping amplitude is determined by the Luttinger liquid effects.
