Quantum Dynamics in Optical Quasicrystals

本计画的目标是在光学准晶中观测多体系统的相干量子多体动力学。在过去的十五年中，光学晶格中的超冷原子已经成为研究周期势场中相互作用粒子多体物理的一个强有力的模型系统。这个博士项目是嵌入到一个更大的项目中，目标是通过实现光学准晶将这种控制水平扩展到准周期势。即使准晶是长程有序的，周期凝聚态系统的许多基本概念，如布洛赫波或布里渊区并不适用。这使它们处于周期性和无序系统之间有趣的中间地带，并突出了它们在新的多体物理学中的潜力。

The goal of this project is the observation of coherent quantum many-body dynamics of many-body systems in an Optical Quasicrystal. During the last fifteen years, ultracold atoms in optical lattices have emerged as a powerful model system to study the many-body physics of interacting particles in periodic potentials. This PhD project is embedded into a larger project with the goal of extending this level of control to quasiperiodic potentials by realizing an optical quasicrystal.Even though quasicrystals are long-range ordered, many foundational concepts of periodic condensed matter systems such as Blochwaves or Brillouin zones are not applicable. This places them on an interesting middle ground between periodic and disordered systems and highlights their potential for novel many-body physics.
