论文摘要
这项工作的目的是将费米量子蒙特卡洛模拟中哈伯德场的方法推广到链接场的情况。引入的Hubbard Link字段起着负责吸引和排斥电子激发在节点处的相互作用场的作用。这种改进导致有关热相关时间，亚稳态状态和数量的概率分布的许多优势。证明使用五个字段的计算在能量可观察的情况下更稳定和可靠。
The aim of this work is to generalize the method of Hubbard fields in fermion Quantum Monte Carlo simulation to the case of link fields. The introduced Hubbard link fields play a role of the interaction fields responsible for the attraction and repulsion of electronic excitations at the nodes. Such improvements leads to a number of advantages concerning thermalization time, autocorrelations, metastable states and probability distributions of the quantities. It is demonstrated that computations using five fields are more stable and reliable in case of energy observables.
