标题： Characterization of the chaotic phase in the tilted Bose-Hubbard model

摘要： 我们从本征态结构和能谱的统计特征出发，确定倾斜玻色-哈伯德模型的混沌相是能量、倾斜强度以及粒子相互作用的函数。 我们的分析表明，裸玻色-哈伯德哈密顿量的混沌相实际上可以通过适度的倾斜得以增强。 我们进一步从冷原子实验中通常采用的均匀密度构型的角度揭示了混沌区域的发展和尺度，并为该系统的未来理论和实验研究提供了宝贵的相图。 显示英文摘要

摘要： The chaotic phase of the tilted Bose-Hubbard model is identified as a function of energy, tilt strength and particle interaction, from the eigenstate structure and the statistical features of the energy spectrum. Our analysis reveals that the chaotic phase of the bare Bose-Hubbard Hamiltonian can actually be enhanced by the presence of a moderate tilt. We further unveil the development and scaling of the chaotic regime from the perspective of a homogeneous density configuration typically used in cold atom experiments, providing a valuable phase diagram for future theoretical and experimental studies of this system.
