Staggered Orbital Currents in a Model of Strongly Correlated Electrons
Strongly Correlated Electrons

Abstract
This preprint has been withdrawn, as the evidence for persistent currents found with the "infinite-size" DMRG algorithm has not been reproduced with the (presumably more accurate) "finite-size" version of the algorithm (M. Troyer and U. Schollwoeck, private communiation). A much clearer example of long-range order in orbital currents is presented in: J. O. Fjaerestad and J. B. Marston, ``Staggered Orbital Currents in the Half-Filled Two-Leg Ladder,'' cond-mat/0107094.

This preprint has been withdrawn. A ladder which exhibits long-range order in staggered orbital currents is discussed in cond-mat/0107094
