Correlation functions in the one-dimensional Hubbard model
Finkel'shtem A.M.
The asymptotic forms of the correlation functions in the one-dimensional Hubbard model, when umklapp processes are significant, are obtained. It is shown that two types of pairing in the ground state are simultaneously realized. The corresponding correlation functions fall off in power-law fashion at large distances.
