Extended Hubbard model on a C molecule
Fei Lin, Erik S. Sørensen, Catherine Kallin +1
The electronic correlations on a C molecule, as described by an extended Hubbard Hamiltonian with a nearest neighbor Coulomb interaction of strength , are studied using q…
Anisotropic Spin Couplings and the Inelastic Neutron Cross Section of NaNiO_2
Laura Filion, Catherine Kallin, A. John Berlinsky +1
This paper has been withdrawn due to an error. We plan to replace it with a corrected version.
Spin Structure Factor of the Frustrated Quantum Magnet Cs_2CuCl_4
Denis Dalidovich, Rastko Sknepnek, A. John Berlinsky +2
The ground state properties and neutron structure factor for the two-dimensional antiferromagnet on the triangular lattice, with uni-directional anisotropy in the nearest-neighbor…
Applications of Cluster Perturbation Theory Using Quantum Monte Carlo Data
Fei Lin, Erik S. Sorensen, Catherine Kallin +1
We study cluster perturbation theory [Phys. Rev. Lett. \textbf{84}, 522 (2000)] when auxiliary field quantum Monte Carlo method is used for solving the cluster hamiltonian. As a ca…
Imaginary chemical potential quantum Monte Carlo for Hubbard molecules
Fei Lin, Jurij Smakov, Erik S. Sorensen +2
We generalize the imaginary chemical potential quantum Monte Carlo (QMC) method proposed by Dagotto et al. [Phys. Rev. B 41, R811 (1990)] to systems without particle-hole symmetry.…
Ordering and Spin Waves in NaNiO2 : A Stacked Quantum Ferromagnet
M. J. Lewis, B. D. Gaulin, L. Filion +5
Neutron scattering measurements on powder NaNiO2 reveal magnetic Bragg peaks and spin waves characteristic of strongly correlated s=1/2 magnetic moments arranged in ferromagnetic l…
