这篇高度跨学科的论文涵盖了与冷原子界面、量子模拟、量子磁学和无序有关的广泛主题。通过一个独立的介绍，它提供了冷原子快速发展领域的广泛概述，并对该领域的本科生和研究人员都感兴趣。从冷原子和光学晶格的物理学的一般介绍开始，它将理论扩展到具有不同多物种原子的系统。它通过对平均场和强关联区性质的广泛研究，推进了（光晶格）激发带中多体量子系统的理论。特别强调的是量子模拟的背景下，如这里所示，在激发带的轨道自由度允许研究的异国情调的磁性模型不容易实现与以前的替代系统。此外，它提出了一个新的模型哈密顿量，作为一个量子模拟器的各种无序系统在不同的对称类，可以很容易地复制实验。这是非常有趣的，特别是对于二维量子系统中的无序的研究。
This highly interdisciplinary thesis covers a wide range of topics relating to the interface of cold atoms, quantum simulation, quantum magnetism and disorder. With a self-contained presentation, it provides a broad overview of the rapidly evolving area of cold atoms and is of interest to both undergraduates and researchers working in the field. Starting with a general introduction to the physics of cold atoms and optical lattices, it extends the theory to that of systems with different multispecies atoms. It advances the theory of many-body quantum systems in excited bands (of optical lattices) through an extensive study of the properties of both the mean-field and strongly correlated regimes. Particular emphasis is given to the context of quantum simulation, where as shown here, the orbital degree of freedom in excited bands allows the study of exotic models of magnetism not easily achievable with the previous alternative systems. In addition, it proposes a new model Hamiltonian that serves as a quantum simulator of various disordered systems in different symmetry classes that can easily be reproduced experimentally. This is of great interest, especially for the study of disorder in 2D quantum systems.
