标题： Exploring Unique Characteristics in Stark Many-Body Localization

摘要： 斯特ark多体局域化（MBL）是在无无序的量子系统中观察到的一种现象，其中存在的线性势，称为斯特ark场，导致了局域化。 我们的研究旨在提供对斯特ark MBL特性的新见解，并发现与该现象相关的独特纠缠特性。 相图分析揭示了不同相互作用强度下的不同行为。 此外，我们强调了畴壁结构对系统纠缠熵破坏的影响。 此外，对时间有序相关函数（OTOC）行为的研究展示了基于畴壁配置的相互作用的不同响应。 我们的发现有助于更好地理解斯特ark MBL，并为受斯特ark势作用的系统的纠缠特性提供了有价值的见解。 显示英文摘要

摘要： Stark Many-Body Localization (MBL) is a phenomenon observed in quantum systems in the absence of disorder, where the presence of a linear potential, known as the Stark field, causes the localization. Our study aims to provide novel insight into the properties of Stark MBL and to discover unique entanglement characteristics specific to this phenomenon. The phase diagram analysis reveals different behavior with varying interaction strengths. Furthermore, we highlight the influence of domain wall structures on the breakdown of the entanglement entropy of the system. Moreover, the investigation of Out-of-Time-Ordered Correlator (OTOC) behavior demonstrates distinct responses to interactions based on domain wall configurations. Our findings contribute to a better understanding of Stark MBL and offer valuable insights into the entanglement properties of systems subjected to Stark potentials.
