Exact Result on Hole Dynamics of One-Dimensional Supersymmetric t-J Model with Long Range Interaction
Yusuke Kato
Abstract
We obtain an exact result on single hole dynamics in one-dimensional Mott-insulators through the study on the supersymmetric t-J model with long range interaction at half-filling. We calculate the expression G1s1h(x,t) for one spinon one holon contribution to the hole propagator. We find that G1s1h(x=0,t=0)=3/8, which amounts to 75% of the spin-fixed mean particle density 1/2.
