Thermodynamic properties of the one-dimensional Kondo insulators studied by the density matrix renormalization group method
N. Shibata, B. Ammon, M. Troyer +2
Thermodynamic properties of the one-dimensional Kondo lattice model at half-filling are studied by the density matrix renormalization group method applied to the quantum transfer m…

Quantum Monte Carlo Loop Algorithm for the t-J Model
Beat Ammon, Hans Gerd Evertz, Naoki Kawashima +2
We propose a generalization of the Quantum Monte Carlo loop algorithm to the t-J model by a mapping to three coupled six-vertex models. The autocorrelation times are reduced by ord…
