Antiholons in one-dimensional t-J models
C. Lavalle, M. Arikawa, S. Capponi +2
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 mo…

Anomalous finite size spectrum in the S=1/2 two dimensional Heisenberg model
C. Lavalle, S. Sorella, A. Parola
We study the low energy spectrum of the nearest neighbor Heisenberg model on a square lattice as a function of the total spin S. By quantum Monte Carlo simulation we compute this s…
