Abstract

We develop a new type of cluster algorithm that strongly reduces the critical slowing down and the frustration effect in Monte Carlo simulations of the 2D quantum antiferro-magnet Heisenberg model (AFMH). The results obtained show that the method can be applied efficiently for the study of the 2D AFMH at lower temperatures.

An Efficient Cluster Algorithm and Its Numerical Study for the Quantum Spin systems

He-Ping Ying, JI DA-REN

Using a blockspin scheme, a cluster algorithm is developed for the numerical study of the quantum spin systems. The method is tested in detail for the ferro- and antiferromagnetic Heisenberg chains, of which our calculations show that the new algorithm can be used to simulate the induced classical spin systems efficiently by strongly reducing the slowing down effects.

Quantum Monte Carlo study of two-dimensional random Heisenberg antiferromagnets

Synge Todo, 眞治 藤堂

Recent improvement of Monte Carlo techniques for quantum magnets, together with contin-ual development of high-performance parallel computers, makes us possible to access precise information about novel and peculiar features of low-dimensional random quantum antiferro-magnets, observed at extremely low energy scale. We give a review on the powerful continuous-time loop algorithm for the world-line quantum Monte Carlo method, and its application to the random quantum Heisenberg antiferromagnts, especially effects of non-magnetic impurities and also of bond randomness on the spin-gapped ground state of the two-dimensional systems. 1

Cluster-Spin Quantum Monte Carlo Study of One-Dimensional Heisenberg Model

Yutaka Okabe, Macoto Kikuchi

The cluster-spin decomposition method is studied for the quantum Monte Carlo simulation based on the Suzuki-Trotter formula. A new vectorized algorithm for the speed-up of the calculation is implemented. We investigate the one-dimensional ferromagnetic and antiferromagnetic Heisenberg models, paying attention to the cluster size of decomposition.

Meron-cluster simulation of the quantum antiferromagnetic Heisenberg model in a magnetic field in one- and two-dimensions

Palma, A. Riveros

Motivated by the numerical simulation of systems which display quantum phase transitions, we present a novel application of the meron-cluster algorithm to simulate the quantum antiferromagnetic Heisenberg model coupled to an external uniform magnetic field both in one and in two dimensions.In the infinite volume limit and at zero temperature we found numerical evidence that supports a quantum phase transition very close to the critical values B c = 2 and B c = 4 for the system in one and two dimensions, respectively.For the one dimensional system, we have compared the numerical data obtained with analytical predictions for the magnetization density as a function of the external field obtained by scaling-behaviour analysis and Bethe Ansatz techniques.Since there is no analytical solution for the two dimensional case, we have compared our results with the magnetization density obtained by scaling relations for small lattice sizes and with the approximated thermodynamical limit at zero temperature guessed by scaling relations.Moreover, we have compared the numerical data with other numerical simulations performed by using different algorithms in one and two dimensions, like the directed loop method.The numerical data obtained are in perfect agreement with all these previous results, which confirms that the meron-algorithm is reliable for quantum Monte Carlo simulations and applicable both in one and two dimensions.Finally, we have computed the integrated autocorrelation time to measure the efficiency of the meron algorithm in one dimension.

A new type of cluster algorithm is developed to simulate the two-dimensional spin one half quantum Heisenberg antiferromagnet (QHAF) on a hexagonal lattice. The numerical results show that the method can be applied to study efficiently the QHAF systems at lowertemperatures, with large Trotter number, on the general bipartite lattices.
