Renormalization of the Spin-Peierls Transition due to Phonon Dynamics
S. Trebst, N. Elstner, H. Monien
We report results from a systematic strong-coupling expansion of a spin-1/2 Heisenberg chain coupled to Einstein phonons. In the non-adiabatic regime this model is used to describe…

A numerical exact solution of the Bose-Hubbard model
Norbert Elstner, Hartmut Monien
In this paper we report results from a systematic strong-coupling expansion of the Bose-Hubbard model in one and two spatial dimensions. We obtain numerically exact results for the…
