Antiholons in one-dimensional t-J models
arXiv:cond-mat/0211054 · doi:10.1103/PhysRevLett.90.216401
Abstract
Using a newly developed hybrid Monte Carlo algorithm for the nearest-neighbor (n.n.) t-J model, we show that antiholons identified in the supersymmetric inverse squared (IS) t-J model are clearly visible in the electron addition spectrum of the n.n. t-J model at J=2t and also for J=0.5t, a value of experimental relevance.
