Welcome to the Walther group at Purdue University!
Our group has research interests that lie at the intersection of theoretical atomic physics, quantum optics and condensed matter physics. A main topic in our research are highly excited Rydberg states and their long-ranged interactions, both in atomic systems and in semiconductors. We investigate how Rydberg states interact with their environment, how their interactions can be effectively described and how they can be used to control the flow of photons. These questions bring us in contact with many exciting questions at the forefront of quantum metrology, quantum optics and quantum computing, such as: How does quantum light propagate through a material? How can fragile quantum many-body states be probed without destroying them? How can we control single photons and implement quantum logical operations with them?
