System von Rydberg Atomen zur Realisierung von bosonischen Topologischen Isolatoren
Zusammenfassung der Projektergebnisse
Within a strong collaboration between the experimental group of Antoine Browaeys we demonstrated that Rydberg atoms in optical tweezers are a highly promising platform for the exploration of topological states of matter. We started with a proof of principle experiments how to design effective magnetic fields using the intrinsic spin-orbit coupling of dipolar exchange interactions. This approach forms the main idea for the theoretical proposals of topological band structures, and we used it in our collaboration to demonstrate that a fractional bosonic Chern insulator can be realized for realistic experimental parameters. This paves the way towards the first implementation of a topological phase in artificial matter. The project helped us the strengthen the extremely fruitful collaboration with the group of Antoine Browaeys. We currently have several ongoing projects together, which build on the success of the present proposal.
