Charge excitations in SU(n) spin chains: exact results for the 1/r^2 model
arXiv:cond-mat/0610268 · doi:10.1103/PhysRevB.75.024405
Abstract
We study the one- and two-holon excitations of the SU(3) Kuramoto-Yokoyama model on the level of explicit wave functions, and generalize the calculations to the case of SU(n). We obtain the exact energies and the single holon momenta, which we find fractionally spaced according to fractional statistics with statistical parameter g=1/n.
