Parallel quantum Monte Carlo: The one-dimensional Kondo insulator

Richard M. Fye, Douglas J. Scalapino

The authors discuss parallelization strategies for the BSS (Blankenbecler-Sugar-Scalapino) algorithm, a quantum Monte Carlo technique for treating lattice fermions. They then present results obtained by applying the BSS algorithm to the one-dimensional Kondo insulator model on both vector and parallel machines. In particular they compare Kondo insulator spin correlations with RKKY predictions, investigate the opening of a charge gap, and consider the question of long-range anti-ferromagnetic order.

Comments on "Dimerization Induced by the RKKY Interaction"

Naokazu Shibata, Chisa Hotta

Recently, Xavier et al. claimed the existence of an insulating spin dimer state in the one-dimensional Kondo lattice model at quarter-filling amidst the paramagnetic metallic phase. In this comment we show that the dimer-dimer correlation decays algebraically at long distances and the charge gap vanishes in the bulk limit.
