Interacting Rydberg excitons in modulated potential landscapes (A08*)

• Subject Area: Experimental Condensed Matter Physics
• Term: from 2019 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 249492093

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.
