抄録

The pairing susceptibility of the one-dimensional t-J model is examined numerically by the quantum transfer matrix method. The temperature dependence of the pairing susceptibility χs shows logarithmic behavior at low temperatures as χs~α log T for T being the temperature. The coefficient α is determined as a function of J/t and the fillingness for J and t being the exchange interaction and the transfer. Beyond that of noninteracting fermions, α grows rapidly with the increase of │J│.
