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. ; Comment: 4 pages, 4 figures
