Within this project, we will study confinement effects on highly excited Rydberg excitons. Their large micrometer-sized spatial extension offers the unique possibility to create confinement potentials without having to resort to nanotechnology. Instead strain traps, optical lattices formed by counter-propagating laser beams or even the finite sample thickness may be used. We will start by studying center of mass-quantization and move to more complex settings such as energy level structures in double traps. Finally, we will set out to investigate periodic trap lattices where Rydberg blockade ensures that each lattice position is occupied only by one exciton, which serve as model systems for a quantum simulator.

在这个项目中，我们将研究高激发里德堡激子的约束效应。他们的大微米尺寸的空间扩展提供了独特的可能性，创造限制潜力，而不必诉诸纳米技术。代替应变陷阱，可以使用由反向传播的激光束或甚至有限的样品厚度形成的光学晶格。我们将从研究质量量子化的中心开始，然后转向更复杂的设置，例如双陷阱中的能级结构。最后，我们将着手研究周期性陷阱晶格，其中里德伯封锁确保每个晶格位置仅被一个激子占据，作为量子模拟器的模型系统。
