Quantum phase transitions in the Triangular-lattice Bilayer Heisenberg Model
Rajiv R. P. singh, Norbert Elstner
We study the triangular lattice bilayer Heisenberg model with antiferromagnetic interplane coupling and nearest neighbour intraplane coupling , which can be…

Dynamics and Thermodynamics of the Bose-Hubbard model
N. Elstner, H. Monien
We report results from a systematic analytic strong-coupling expansion of the Bose-Hubbard model in one and two spatial dimensions. We obtain numerically exact results for the disp…
