Electronic and magnetic properties of the ionic Hubbard model on the striped triangular lattice at 3/4 filling
J. Merino, R. H. McKenzie, B. J. Powell
We report a detailed study of a model Hamiltonian which exhibits a rich interplay of geometrical spin frustration, strong electronic correlations, and charge ordering. The characte…
Teleportation via multi-qubit channels
Jon Links, John Paul Barjaktarevic, Gerard J. Milburn +1
We investigate the problem of teleporting an unknown qubit state to a recipient via a channel of qubits. In this procedure a protocol is employed whereby Bell state measur…
Measurement-Based Teleportation Along Quantum Spin Chains
J. P. Barjaktarevic, J. Links, G. J. Milburn +1
We consider teleportation of an arbitrary spin-1/2 target quantum state along the ground state of a quantum spin chain. We present a decomposition of the Hilbert space of the many…
Metal-insulator transition and charge ordering in the extended Hubbard model at one-quarter filling
M. Calandra, J. Merino, Ross H. McKenzie
We study with exact diagonalization the zero temperature properties of the quarter-filled extended Hubbard model on a square lattice. We find that increasing the ratio of the inter…
Integrability and exact spectrum of a pairing model for nucleons
J. Links, H. -Q. Zhou, M. D. Gould +1
A pairing model for nucleons, introduced by Richardson in 1966, which describes proton-neutron pairing as well as proton-proton and neutron-neutron pairing, is re-examined in the c…
Exact solution at integrable coupling of a model for the Josephson effect between small metallic grains
J. Links, H. -Q. Zhou, R. H. McKenzie +1
A model is introduced for two reduced BCS systems which are coupled through the transfer of Cooper pairs between the systems. The model may thus be used in the analysis of the Jose…
