We present a description of the ground state and low-lying excited states of two holes in the 4 x 4 cluster t-J model in terms of a simple model for the motion of a single bipolaron. The existence of short-range antiferromagnetic correlations has been assumed. According to the suggested scenario, th
The bound states of p holes are studied within the two-dimensional two-band model with the antiferromagnetic exchange interaction between d and p spins, J. The binding energies of p holes are computed as a function of the Cu-O transfer and one of J within the mean-field theory with the periodic boun
