Fate of partial order on the trillium and distorted windmill lattices
Sergei V. Isakov, John M. Hopkinson, Hae-Young Kee
The classical Heisenberg model on the trillium and distorted windmill lattices exhibits a degenerate ground state within large- theory, where the degenerate wavevectors form a s…

The optical conductivity of half-filled Hubbard ladders
J. Hopkinson, K. Le Hur
We investigate the optical conductivity of half-filled N-leg Hubbard ladders far into the ``deconfinement'' limit (i.e., weak Hubbard interaction and relatively strong interchain h…

Susy atomic model
J. Hopkinson, P. Coleman
We present the simplest model to which one can apply the supersymmetric Hubbard operators recently introduced. For the atomic model, , where is a H…
