摘要：
The spectral function of the one-dimensional (1D) and two-dimensional (2D) t-J models is examined in connection with spin and charge dynamics by using the exact diagonalization technique. Near half filling, the spectral functions in 2D reveal a two-peak structure which is due to different dynamics of spin and charge degrees of freedom. This is compared with the behavior of the spectral function in 1D, and the implication of the result is discussed.
