摘要

在冷原子系统领域,挫折对扩展超固态的影响在很大程度上是一个尚未探索的课题。在这项研究中,我们探索了准晶格对双极玻色子超固态的影响。我们的研究结果表明,弱准晶格能诱导多种调制相,将固有的固体模式与外部电势诱导的准周期装饰融合在一起。随着晶格变得越来越强,我们观察到了超准晶相和玻色玻璃相。我们的研究结果得到了使用镝原子和准晶格光电势进行实验可行性的详细讨论的支持,为探索非周期性环境中长程相互作用量子系统开辟了一条新途径。我们为未来的实验研究提供了坚实的基础,有可能证实我们的理论预测,并对复杂外部势中的量子气体领域做出深远的贡献。

Exploring Quantum Phases of Dipolar Gases through Quasicrystalline Confinement
The effects of frustration on extended supersolid states is a largely unexplored subject in the realm of cold-atom systems. In this work, we explore the impact of quasicrystalline lattices on the supersolid phases of dipolar bosons. Our findings reveal that weak quasicrystalline lattices can induce a variety of modulated phases, merging the inherent solid pattern with a quasiperiodic decoration induced by the external potential. As the lattice becomes stronger, we observe a superquasicrystal phase and a Bose glass phase. Our results, supported by a detailed discussion on experimental feasibility using dysprosium atoms and quasicrystalline optical lattice potentials, open a new avenue in the exploration of long-range interacting quantum systems in aperiodic environments. We provide a solid foundation for future experimental investigations, potentially confirming our theoretical predictions and contributing profoundly to the field of quantum gases in complex external potentials.
