TL;DR

This paper demonstrates that the Hellberg-Mele Jastrow factor serves as an effective variational wave function for accurately modeling the one-dimensional XXZ spin chain.

Contribution

It introduces the Hellberg-Mele Jastrow factor as a highly effective variational wave function for the 1D XXZ model, expanding its applicability beyond the t-J model.

Findings

The Jastrow factor provides an excellent variational description of the XXZ model.

The approach improves understanding of wave functions in one-dimensional quantum spin systems.

The method offers a promising tool for studying similar models.

Abstract

We find the Jastrow factor introduced by Hellberg and Mele in their study of the one dimensional t-J model provides an exceedingly good variational description of the one dimensional XXZ model.
