Spinon-Holon Attraction in the Supersymmetric t-J Model with 1/r^2-Interaction

Abstract

We derive the coordinate representation of the one-spinon one-holon wavefunction for the supersymmetric $t-J$ model with $1/r^2$-interaction. This result allows us to show that spinon and holon attract each other at short distance. The attraction gets stronger as the size of the system is increased and, in the thermodynamic limit, it is responsible for the square root singularity in the hole spectral function.
