Parametrized canonical transformation for the Hubbard-model at arbitrary interaction strength
Balazs Hetenyi, Hans Gerd Evertz
The and Heisenberg models are truncated expansions of a canonically transformed Hubbard model coinciding with it at . We show that a modified canonical transform…

Loop updates for variational and projector quantum Monte Carlo simulations in the valence-bond basis
A. W. Sandvik, H. G. Evertz
We show how efficient loop updates, originally developed for Monte Carlo simulations of quantum spin systems at finite temperature, can be combined with a ground-state projector sc…

Efficient Matrix Product State Method for periodic boundary conditions
Peter Pippan, Steven R. White, Hans Gerd Evertz
We introduce an efficient method to calculate the ground state of one-dimensional lattice models with periodic boundary conditions. The method works in the representation of Matrix…
