摘要
We present results for singlet and triplet pairing correlation functions of the one dimensional t-J model obtained via exact diagonalization of finite systems. The general behavior found supports the predictions by the Luttinger liquid picture, especially a size analysis of the critical behavior near k = 0 gives the same critical exponents for both correlation functions. The relative magnitude of the singlet pairing correlations to the triplet ones is examined in this connection. In addition, the magnetic field effect on the pairing correlations is also studied.
