Numerical evaluation of the partition function for one-dimensional quantum systems

I. Morgenstern, Diethelm Würtz

Publisher

Abstract

We present a ``numerically exact'' method to obtain the partition function of one-dimensional quantum systems. The method is suitable for Cray I supercomputers. As an example, for the potential of the method we publish results for random XY and Heisenberg chains.

A simple Monte Carlo method to evaluate the partition function of quantum spin systems is proposed. The method is applied to the isotropic spin-1/2 Heisenberg system of one-dimension and excellent agreements are obtained with the numerically rigorous result of Bonner and Fisher.

A New Monte Carlo Approach to Quantum Spin Systems: Direct Evaluation of the Partition Function

Shinji Kadowaki, A. Ueda

A simple Monte Carlo high-temperature expansion method to evaluate the partition function of quantum spin systems which was proposed in the previous paper l) is improved so that all of the needed expansion-coefficients are obtained from interpolating points of less than ten with an interpolation formula. By this improvement, this method is applicable to the finite spin-systems of rather large spin size regardless of dimensionality of the system. As an example, the method is applied to the one-dimensional spin-l/2 isotropic Heisenberg ferromagnetic system.

Thermodynamical properties of quantum many-body systems

Eduardo R. Gagliano, S. Bacci

We present a method to compute exactly the partition function of quantum many-body systems. This approach involves the evaluation of a set of coefficients for the continued-fraction expansion of a resolventlike operator. The main advantage of this method is that this set of coefficients is unique and allows one to calculate the partition function at any temperature. As an illustration, the method is applied to a simple one-dimensional spinless model.

Polynomial-time Classical Simulation for One-dimensional Quantum Gibbs States

Tomotaka Kuwahara, Keiji Saito

This paper discusses a classical simulation to compute the partition function (or free energy) of generic one-dimensional quantum many-body systems. Many numerical methods have previously been developed to approximately solve one-dimensional quantum systems. However, there exists no exact proof that arbitrary one-dimensional quantum Gibbs states can be efficiently solved by a classical computer. Therefore, the aim of this paper is to prove this with the clustering properties for arbitrary finite temperatures $β^{-1}$. We explicitly show an efficient algorithm that approximates the partition function up to an error $ε$ with a computational cost that scales as $n\cdot {\rm poly}(1/ε)$, where the degree of the polynomial depends on $β$ as $e^{O(β)}$. Extending the analysis to higher dimensions at high temperatures, we obtain a weaker result for the computational cost n\cdot (1/ε)^{\log^{D-1} (1/ε)}, where $D$ is the lattice dimension.
