Discerning Incompressible and Compressible Phases of Cold Atoms in Optical Lattices
V. W. Scarola, L. Pollet, J. Oitmaa +1
Experiments with cold atoms trapped in optical lattices offer the potential to realize a variety of novel phases but suffer from severe spatial inhomogeneity that can obscure signa…

The Spin-1 Heisenberg Antiferromagnet: New Results from Series Expansions
J. Oitmaa, C. J. Hamer
We calculate ground state properties (energy, magnetization, susceptibility) and one-particle spectra for the Heisenberg antiferromagnet with easy-axis or easy-plane single…

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…
