标题： Quantum simulation of the phase transition of the massive Thirring model

摘要： 量子计算技术的快速发展使得通过在量子计算机上的量子模拟研究费米系统在有限温度下的热力学性质成为可能。 这为研究费米系统的手征相变提供了一种新方法。 其中，量子最小纠缠典型热态（QMETTS）算法最近引起了广泛关注。 该大质量Thirring模型在低温下表现出多种现象，包括手征相变和拓扑非平凡的基态。 因此，提出了一个引人入胜的问题，即是否可以使用量子模拟方法来研究其相变。 在本研究中，利用QMETTS算法研究了大质量Thirring模型的手征相变及其对偶拓扑相变。 结果表明，QMETTS能够准确再现大质量Thirring模型的相变和热力学性质。 显示英文摘要

摘要： The rapid development of quantum computing technology has made it possible to study the thermodynamic properties of fermionic systems at finite temperatures through quantum simulations on a quantum computer. This provides a novel approach to the study of the chiral phase transition of fermionic systems. Among these, the quantum minimally entangled typical thermal states (QMETTS) algorithm has recently attracted considerable interest. The massive Thirring model, which exhibits a variety of phenomena at low temperatures, includes both a chiral phase transition and a topologically non-trivial ground state. It therefore raises the intriguing question of whether its phase transition can be studied using a quantum simulation approach. In this study, the chiral phase transition of the massive Thirring model and its dual topological phase transition are studied using the QMETTS algorithm. The results show that QMETTS is able to accurately reproduce the phase transition and thermodynamic properties of the massive Thirring model.
