用里德伯原子构造分形序和相变

Construction of Fractal Order and Phase Transition with Rydberg Atoms

Nayan E. Myerson-Jain, Stephen Yan, David Weld, Cenke Xu

摘要:

我们提出了利用里德伯原子阵列来构造具有分形结构的物质多体相。该相的简并低能激发态形成自相似分形结构。该阶段类似于所谓的“II型分形子拓扑状态”。在标准凝聚态平台中实现类分形模型的主要挑战是多自旋相互作用的产生,因为现实系统通常由两体相互作用主导。在这项工作中,我们证明了范德华相互作用和实验的可调谐性的里德伯为基础的平台,使模拟具有分形结构的物质的异国情调的阶段,和研究的量子相变涉及分形有序相。

英文摘要:

We propose the construction of a many-body phase of matter with fractal structure using arrays of Rydberg atoms. The degenerate low energy excited states of this phase form a self-similar fractal structure. This phase is analogous to the so-called "type-II fracton topological states". The main challenge in realizing fracton-like models in standard condensed matter platforms is the creation of multi-spin interactions, since realistic systems are typically dominated by two-body interactions. In this work, we demonstrate that the Van der Waals interaction and experimental tunability of Rydberg-based platforms enable the simulation of exotic phases of matter with fractal structures, and the study of a quantum phase transition involving a fractal ordered phase.
