Hard Core Bosons on the Triangular Lattice at Zero Temperature: A Series Expansion Study
J. Oitmaa, Weihong Zheng, D. Tompsett
We use high order linked cluster series to investigate the hard core boson model on the triangular lattice, at zero temperature. Our expansions, in powers of the hopping parameter…

Magnon and Hole Excitations in the Two-Dimensional Half-filled Hubbard Model
Weihong Zheng, Rajiv R. P. Singh, J. Oitmaa +2
Spin and hole excitation spectra and spectral weights are calculated for the half-filled Hubbard model, as a function of . We find that the high energy spin spectra are sensit…
